Answer:
x = -4
Step-by-step explanation:
Write and solve an equation in which the slope from the definition of slope is on the left side and the given slope, 4/7, is on the right side:
7 - 5 4
m = ---------- = --------
3 - x 7
Simplifying with the aim to find the value of x:
2(7) = 4(3 - x), or 7 = 3 - x. Then x = -4.
