Question

Give the slope of y-4 = 5(x-2) and a point on the line.

A. The slope is 5 and (2,4) is on the line.
B. The slope is 4 and (2,5) is on the line.
C. The slope is 5 and (-2,-4) is on the line.
D. The slope is 2 and (5, 4) is on the line.

Answer 1

A

Explanation:

y -4 = 5(x-2)

Distributive property

y -4 = 5x -10

Inverse operation

y-4 = 5x -10

+4. +4

y = 5x - 6

m = 5

4 = 5(2) - 6

4 = 10 - 6

4 = 4
