Question

y = mx + b y = kx + 4 d = kc + 4 k is the slope. What is the slope of the line? A) (d - 4)/c B) (d + 4)/c C) (c - 4)/d D) (c + 4)/d

Answer 1

A

Explanation:

given

d = kc + 4 and k is the slope

isolate the term with k by subtracting 4 from both sides

d - 4 = kc + 4 - 4 ( simplify right side )

d - 4 = kc ( isolate k by dividing both sides by c )

`(d-4)/(c)` = k
