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.

  • calculus -

    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
