Question 7 of 25

2 Points
Give the slope of y- 3 = 4(x+8) and a point on the line.
O
A. The slope is 4 and (-8,3) is on the line.
O
B. The slope is 4 and (8, -3) is on the line.
O
C. The slope is 3 and (-8, 4) is on the line.
O
D. The slope is 8 and (3, 4) is on the line.

Answer 1

A

Explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = 4(x + 8) ← is in point- slope form

with slope m = 4 and (a, b) = (- 8, 3) → A
