d is the answer

slope = (y2 - y1) / (x2 - x1)
by substitution
slope = (3 - 0) / [(4) - (-3)]
= 3/7

the slope is rise / run, so the amount that changes divided by the amount x changes

in this equation y increases by 7 when x increases by 3

thus the answer is D 3/7

m = (y2-y1)/(x2-x1)
m = (3 - 0)/(4 - (-3))
m = 3/7
