Question

Choose the equation below that represents the line that passes through the point (7, -2) and has a slope of -3

A. y - 2 = -3(x + 7)
B. y + 2 = -3(x - 7)
C. y + 7 = -3(x - 2)
D. y - 7 = -3(x + 2)

Answer 1

I think it’s B to be honest

Answer 2

B

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

Here m = - 3 and (a, b) = (7, - 2 ), thus

y - (- 2) = - 3(x - 7) , that is

y + 2 = - 3(x - 7) → B
