Y=Mx +b
B is 0 because that’s where the graph intercepts the y axis.
M is found by picking any two points and finding the rise and run because m is equal rise/run
Points of choice: (-2,4) and (2,-4)
=2−1/2−1 = -8/4
m is equal -2
Y= -2X
Look at the picture below to differentiate between positive and negative slopes.
Answer: The predictor variable in this problem is the amount spent on promotional material.
Explanation:
A predictor variable refers to variable needed to make a prediction of another variable. If we analyze the problem, we notice that the supermarket chain is predicting the sales revenue generated because once the supermarket spends on promotional material, it will result to sales revenue. Thus, the predictor variable is the amount spent on promotional material.

Think of variable K as number of trees planted and variable J as number of minutes it takes to plant the trees.
K = _J + _
For every 4 trees planted it takes 2 minutes to plant them, so we now have -4/2. 4 is negative because we don't have an unlimited amount of trees to plant. With this being said, we can use this fraction as J.
K = -4/2J + _
We lose 4 trees every 2 minutes, but how many trees did we initially start out with? According to the graph, we started with 28 trees, so K = -4/2J + 28.
Now we can test this equation out by picking a random dot on the graph: 24/2.
24 = -4/2(2) + 28
24 = -4 + 28
24 = 24
This statement is correct, so our equation is correct.
