Answer:
-5x+4y=20
Explanation:
A line passes through point (-8, -5) and has a slope of 5/4
Write an equation in Ax+By=C form for this line.
Use integers for A, B, and C.
So we have a point and a line we can use the point slope formula
y-y1=m(x-x1)
y-(-5)=(5/4)(x- -8)
y+5=(5/4)(x+8)
y=5/4x+10-5
y=5/4x+5
Then we multiply 4 both sides
4y=5x+20
-5x+4y=20
