What is an equation of the line that passes through the points (1,-7) and (-4,8) and put it in fully reduced form

equation of line passing through (1,-7)( -4,8)

First let's find slope (m)

m = (8+7)/(-4-1)

= 15/-5 = -3

(x1,y1) = (1,-7)

Plugging above value in

y - y1 = m( x-x1)

y+7 = -3( x-1)

y+7 = -3x +3

y+3x +4=0
