see below...

Explanation:

let's suppose the image A is a triangle with one coordinates of (3,5) and other two are unknown and we don't even wanna know them but it would be better if we do know them.

And we have a graph.
let's draw a line y=2 on the graph and draw the triangle.

Put the coordinates.

now the coordinates (3,5) are 3 boxes away from the line y=2. so we plot this coordinate three boxes down the line y=2 and do the same for other coordinates so (w,x) is one box away from line y=2 so we plot the coordinates one box down the line y=2. Like the one show below. and your whole graph is done. At the end read the coordinates (w,x) and (y,z) and write them.
