Find an equation oif the line that contains the two points. Write the equation in the general form Ax+By+C=0.

(-5,4)and(2,-5)

Can anyone please teach me how to do this???
I got no idea with writing the equation in the general form.

1. There is two points given (-5,4)&(2,-5)
find slope, m = (-5-4)/(2--5)
=-9/7
y=mx +b
4=(-9/7)(-5) +b
b=-17/7
y=(-9/7)x +(-17/7)
7y =-9x -17
9x+7y+17=0
