The general method to solve such problems is as below.
Suppose the points are (x1,y1) and (x2,y2).
Then the reqd. equation is %28y+-+y1%29%2F%28y2+-+y1%29=%28x+-+x1%29%2F%28x2+-+x1%29.
Here x1 =0, x2 = 5, y1 = 7, y2 = 2.
So the equation is %28y+-+7%29%2F%282+-+7%29=%28x+-+0%29%2F%285+-+0%29
or %28y+-+7%29%2F%28+-+5%29=x%2F5
or y+-+7=-x
or x%2By=7
