Question

Complete the point-slope equation of the line through (-8,-1) and (-6,5)

y-5=

Answer 1

y-5=3x+2

Explanation:

1) to make up the equation through the given two points:

`(x+8)/(-6+8)= (y+1)/(5+1); \ => \ y=3x+24`

2) to change that equation according to the condition:

y-5=3x+24-5; ⇔ y-5=3x+19.

P.S. the way suggested above is not the shortest one.
