Question

Write (-3, -5) (-1, -19) in point slope form

Answer 1

(y + 5) = -7(x + 3)

Explanation:

Point Slope Form: (y - y1) = m(x - x1)

Step 1: Find Slope

m =
`(y2 - y1)/(x2 - x1)`

m =
`(-19 - (-5))/(-1 - (-3))`

m =
`(-19 + 5)/(-1 + 3)`

m =
`(-14)/(2)`

m = -7

Step 2: Put into point slope form

Point Slope Form: (y - y1) = m(x - x1)

(y - (-5)) = -7(x - (-3))

(y + 5) = -7(x + 3)
