Answer:

Given points (-8, -4) and (4,5)

Explanation:

The equation of the line is given by

y - y1 = ((y2 - y1)/(x2 - x1)) (x-x1)

y + 4 =( 5+4)/ (4+8) ( x +8 )

y + 4 = 9/12 (x+ 8 )

y + 4 = 3/4 (x + 8)

4( y + 4 ) = 3(x + 8)

4y + 16 = 3x + 24

3x + 24 - 4y - 16 = 0

3x - 4y +8 = 0

Which is the required equation
