Question

Write an equation of a line in point-slope form that has a slope of -2 and passes through (5, -1).
A. y + 1 = -2(x – 5)
B. y – 1 = -2(x – 5)
C. y – 5 = -2(x + 1)
D. y -5 = -2(x – 1)

Answer 1

the formula is (y - y1) = m(x - x1)

m = slope, substitute the points what do you get ?

Answer 2

y -5 = -2(x – 1) ?

Answer 3

you have

y - (-1) = -2 (x -5) points (5,-1) (x,y)
