Answer:
Step-by-step explanation:
The big hint is what happens when x = 0?
The answer is y = - 7
So that means that the y intercept is- 7.
So far, what you know is y = mx - 7
Use any one of the other polnts to determine m
I'll use (2 , - 17), but there's nothing special about this point other than it is on the line.
y = mx - 7
x = 2
y = -17
-17 = 2x - 7 Add 7 to both sides
-17+7 = 2x-7+7
-10 = 2x Divide by 2
-10/2 = 2x/2
x = - 5
Equation: y = - 5x - 7
