Question

If p(x,y),q(3,4) and r(-5,-6) are collinear then show that 5x=4y-1.​

Answer 1

Step-by-step explanation:

if they are collinear the area will be 0

 

take x1=5  y1 =2   x2=-3  y2=4  x3=x   y3=y

x1(y2-y3)+x2(y3-y1)+x3(y1-y2) = 0

5(4-y)+(_3)(y-2)+x(2-4)=0

20-5y-3y+6-2x=0

-2x-8y+26=0

-2(x+4y-13)=0

     x+4y-13=0

I hope that's helpfull so mark me brainlist.
