In this photo of the Convention Center in Columbus, Ohio,
there are horizontal and vertical lines on the building. There are also lines that are slanted.
Using your mouse select a point on the photo.
Notice that the (x,y) coordinates are identified using the bottom left corner of the photo as the origin (0,0).
Using your mouse identify the (x,y) coordinates for two points on the green line segment on the building.
Name the first point A and the second point B. Point B should be to the right of Point A.

Point A (x coordinate): Point A (y coordinate):

Point B (x coordinate): Point B (y coordinate):

From these two points calculate the slope of your line.
Remember, the origin(0,0) is the bottom left corner of the picture.
