Question

If the points ( x, y) , (-5,-2) and (3,-5) are collinear point , prove that 3x+8y+31=0

Answer 1

you can solve it ba this way

Answer 2

if three points are collinear then slope of all the points in pair be equal. Taking two first two points and last two points we get (-2-y)/(-5-x) = (-5+2)/(3+5).
solve it.here's your answer
