%289-5%29%2F%28x-4%29+=+2,
4%2F%28x-4%29+=+2,
4+=+2%28x-4%29,
2+=+x-4,
x = 6.

(x,9)and(4,5) m=2
..
slope m = y2-y1/x2-x1 where (x1,y1)& (x2,y2) are the points
m= 5-9 / 4-x
2= -4/(4-x)
multiply by (4-x)
2(4-x)=-4
8-2x=-4
-8
-2x=-8-4
-2x=-12
/-2
x=6
..
similarly you can work on the next problem. you will walk through
