Ireally need i need it in the form of y= mx + b

(y - y1) = m (x -x1)

( y - 5/2) = -1/2 (x - -2)

(y - 5/2) = -1/2 ( x + 2)

y - 5/2 = -1/2 x - 1

y = -x/2 - 1 + 5/2

y = -x/2 - 2/2 + 5/2

y = -x/2 + 3/2

if you need it in y = mx + b form you will have to tell me what b is or I cannot help you. I need the point of intersection on the line of y

Why.. any work.. u got or are u upset..
