Answer:
A
Step-by-step explanation:
First thing is first, the equation has to be negative because the Y is shrinking as the X is growing. So that eliminates B and D as answers. Next, you have to find the slope. That can be find via rise/run. The slope is 1/5.
Answer:
C
Step-by-step explanation:
y = mx + c
m = gradient
c = y-intercept
m = change in y / change in x = [tex]\frac{12-22}{4-2}[/tex] = [tex]\frac{-10}{2}[/tex] = -5
to find c:
rearrange the equation and substitute the values
c = y - mx
c = 22 - (-2 * 5) = 22 - (-10) = 32
y = -5x + 32
