Answer:
D
Explanation:
f(x) = mx + b
f(x) = 1/2 x - 2
m is the slope (1/2) and b is the y-intercept (b) -2.
Only graphs C and D cross the y axis at -2 . That is the point (0, -2)
The slope is 1/2. That means a rise of 1 space up and a run of 2 spaces left.
If you start at the point (0,-2) and go up 1 space and 2 spaces right, you end up back on the line at the point (4,0).
