Question

What is the point slope form of the line with slope −1/4 that passes through the point (−2, 9) ?

Answer 1

Explanation:

slope = -1/4 ;(-2,9)

Point slope form : y- y₁ = m(x-x₁)

y - 9 = -1/4 (x - [-2])

y -9 = -1/4 (x + 2)

y - 9 =-1/4x - (1/4) * 2

y - 9 = -1/4x - 1/2

y = *1/4x - 1/2 + 9

y = -1/4x + 17/2
