Question

Which equation, in point-slope form, represents a line with m=-15 that goes through the point (7,-1)?

Answer 1

D

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 = - 15 and (a, b) = (7, - 1), thus

y - (- 1) = - 15(x - 7), that is

y + 1 = - 15(x - 7) → D
