You can put this solution on YOUR website!
(x,y) = (4,-8)
(x1,y1) = (-10,1)
m = (y-y1))/(x-x1)
m = (-8-1)/(4-(-10)
m = -9/14
.
y = -9/14x + b
.
use the point (4,-8) to find 'b'
.
-8 = -9/14(4) + b
-8 = -36/14 + b
-8 + 36/14 = b
b = -112/14 + 36/14
b = -76/14
.
y = -9/14*x -76/14
.
multiply by 14
.
14y = -9x -16
.
9x + 14y = -16
.
