The positive integers are: +2, +11, +8, 28, and 13
the negative integers are: -7, -9, -11, and -3
the 0 should go in the circle between the two charts
You are correct about the y-intercept. In case you are unsure about the slope, you can check using y1 - y2 / x1 - x2:
(0, -1) and (1, 2)
-1 - 2 / 0 - 1
-3 / -1
3
The slope is 3; you chose the correct answer, great job.
Answer:

Step-by-step explanation:
We want to solve for
in 
We expand to get:
We group similar terms to get:

This simplifies to 
Divide both sides by 7.8 to get

% decrease = change/original price x 100%
= (1200 - 900)/1200 x 100%
= 300/1200 x 100%
= 25%
Therefore, the number of pumpkins sold decreased by 25%.
Yes, it is a rhombus because the diagonals are congruent.
