Answer:
C
Step-by-step explanation:
First, find the slope:
Formula for slope:
m = y2 - y1 / x2 - x1
m = -2 - -5 / 0 - -1
m = - 2 + 5 / 0 + 1
m = 3 / 1
m = 3
Next, find the y-intercept:
When x = 0, y = ???
According to the chart, when x = 0, y = -2. This is our y-intercept, also known as b.
Format the answers:
y = 3x + -2
y = 3x - 2
Check your work:
Plug in any x value and the y value should match the chart:
-5 = 3(-1) - 2
-5 = -3 - 2
-5 = -5
Correct
