Question

find the equation of the lines passing through the following pairs of points A(-4,6),B(8,-3)

Answer 1

equation of the line passing through A and. B
is. (y-6)= -3-6/8-(-4). {x-(-4)}
i.e (y-6) = -9/12 {x+4}
12(y-6)= -9(x+4)
12y-72= -9x-36
9x +12y-72+36=0
9x+12y-36=0
we can also simplify this to
3x+4y-12=0
