Answer: y = 11 when x = -3
Explanation:
To determine the value of y when x equals -3, we can do this in a few different ways. I will show you two here.
The first method is to substitute x = -3 back into the equation, and then solve for y.
Given:
y = -3x + 2
Substitute:
y = -3(-3) + 2
Multiply:
y = 9 + 2
Add:
y = 11
The second method is to graph the given equation. We are given a y-intercept of 2 and a slope of -3. Then, we will find what y equals when x equals -3. I have attached a picture of this graph below.
