Find the slope and y-intercept of the following graph.
Answers
Answer:
y-intercept: 3
slope: 2/3
Step-by-step explanation:
The y-intercept is the point that crosses the y-axis. In this case the y-intercept is 3.
When figuring out the slope, there are some methods. I am going to be using the rise over run method. Start at one point and go up and over untill it hits another point on a graph. Start at (-3,1). Go up 4. Go over 6. You will land on the point (3,5). Your answer will be 4/6. Simplify 4/6 and then you will get 2/3.

which equation represents a line that passes through points (0, 6) and (2, 0) y = -1/3x + 2 y = -1/3x + 6 y = -3x + 2 y = -3x + 6
Answers
The answer is y = 3x + 6. I corrected it to 3x becuase it wouldn't work if it was -3x. If -3x is one of the choices then mark that as the answer.
which equation represents a line that passes through points (0, 6) and (2, 0)
y = -1/3x + 2
y = -1/3x + 6
y = -3x + 2
y = 3x + 6
We have to plug in the coordinates into the equation. If x or y solved from the equation equal a coordinate in the coordinates, then it will be the correct equation.
1) 6 = -1/3x + 2
-1/3x = 4
x = 12
This equation doesn't work. Even if the other pair works, it still doesn't satisfy (0,6).
2) 6 = -1/3x + 6
-1/3x = 0
x = 0
0 = -3x + 2
-3x = -2
x = 2/3
This equation doesn't work. Even if the other pair works, it still doesn't satisfy (2,0).
3) 6 = -3x + 2
-3x = 4
x = -4/3
This equation doesn't work. Even if the other pair works, it still doesn't satisfy (0,6).
4) 6 = 3x + 6
3x = 0
x = 0
0 = 3x + 6
3x = 6
x = 2
This equation works.

Tristan is selling plastic and wooden picture frames. He sells 7 frames total. The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames. How many of each type of frame does Tristan sell?
Answers
Answer:
4 wooden and 3 plastic
Step-by-step explanation:
4 (wooden) × 2 - 5 = 3 plastic
3 (plastic) + 4 (wooden) = 7 total
The number of plastic frames is 4 and the number of wooden frames is 3.
What is equation?
A formula known as an equation uses the equals sign to denote the equality of two expressions.
Given statement:
The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames.
The total number of frames sold by Tristan is 7.
Write the equation for the above statement,
p = 2w - 5
Here, p is a plastic frame and w is a wooden frame,
p + w = 7
Solve the equation by using the elimination method,
p = 4 and w = 3
Therefore, the number of plastic frames is 4 and the number of wooden frames is 3.

Nathan used 2(5/6) loaves of bread to make sandwiches for a lunch. He made equal numbers of 4 different types of sandwiches.
What fraction of a loaf of bread did Nathan use for each type of sandwich?
Answers
Answer:
A)
[tex]\displaystyle \frac{1}{12}[/tex]
B)
[tex]\displaystyle \frac{3}{5}[/tex]
C)
[tex]\displaystyle \frac{17}{24}[/tex]
Step-by-step explanation:
Part A)
The Hendersons were traveling 1/3 of the distance on the first day.
However, they had to stop, having only traveled 1/4 of the 1/3 distance.
So, we can multiply the two fractions together.
Therefore, the fraction of the total distance they traveled is given by:
[tex]\displaystyle \frac{1}{4}\times\frac{1}{3}=\frac{1}{12}[/tex]
The Hendersons traveled 1/12 of the total distance.
Part B)
We are assuming the bottle of milk was full at the beginning.
So, at the beginning, there were 1/1 bottle of milk left.
Howie fed a piglet 1/5 of the bottle. So, there is now:
[tex]\displaystyle 1-\frac{1}{5}[/tex]
Of the bottle left.
Making common denominators and subtracting yields:
[tex]\displaystyle =\frac{5}{5}-\frac{1}{5}=\frac{4}{5}[/tex]
So, after feeding the piglet, 4/5 of the bottle of milk was still there.
3/4 of the remainder was fed to a calf.
So, the amount that was fed to the calf is 3/4 times 4/5. Therefore:
[tex]\displaystyle \frac{3}{4}\times\frac{4}{5}[/tex]
Multiply:
[tex]\displaystyle =\frac{12}{20}=\frac{3}{5}[/tex]
So, the calf drank 3/5 of the bottle of milk.
Part C)
Nathan used 2 (5/6) loaves of bread to make 4 sandwiches.
First, convert 2 (5/6) to an improper fraction. So:
[tex]\displaystyle 2\frac{5}{6}=\frac{12+5}{6}=\frac{17}{6}[/tex]
Nathan made 4 sandwiches using this. So, we will divide this by 4. Note that this is the same as multiplying by 1/4. Therefore:
[tex]\displaystyle \frac{17}{6}\times\frac{1}{4}=\frac{17}{24}[/tex]
So, Nathan used 17/24 loaves of bread per sandwich.

To find:
To complete the pentagon, choosing only from the points below. (2, 0), (–2, 0), (–2, 4), (2, 4).
How can Isabelle complete her pentagon?
Solution:
Consider the attached figure, while going through the following steps.
A five sided polygon is called the pentagon.
As Isabelle already plotted and connected the three points, we need to connect the remaining 2 points to obtain a pentagon.
So, from the attached figure, it's clear that, Isabelle needs to connect the points (2, 0) and (2, 4).
By plotting and connecting these above points, Isabelle can complete her pentagon.
