Question

Which equation, in point-slope form, represents a line with m= -4/7 that goes through the point (-1, 4)?

A) y-4= -4/7(x+1)
B) y+1= -4/7(x-4)
C) y-1= -4/7(x+4)
D) y+4= -4/7(x-1)

And how did you get that Answer

Answer 1

A is the correct answer.

Point Slope Form: y - y₁ = m(x - x₁)

m = slope ⇒ -4/7
Coordinate: (-1 , 4)
x₁ y₁

All you have to do is plug in all of the information above into the formula.

y - 4 = -4/7(x +1)
