C is your answer. The coefficient on the x value is always a stretch factor.
Answer:
i/=-d:./k/-= sorry
Step-by-step explanation:
The slope for the first one would be:
y2-y1/x2-x1, so replace those with the coordinates and you'll get:
-3-1/-7-(-7) => -4/0 so I guess the slope is zero
the slope for the second one would be:
-3-(-3)/5-(-4)=> 0/9 I think this one would be undefined.
Check to make sure, though!
Let's simplify step-by-step.
