The line would start at the bottom of the distance versus time graph and start to move up at a constant speed (straight diagonal line) for 4 minutes then there would be a straight horizontal line representing the time she was not moving, so 3 minutes. Then another straight diagonal line representing her walking for 2 minutes after talking to Maria.
A = 1/2bh
22 = 1/2(2)(h)
22 = h
Hope this helps :)
The slope is 1/4 and the y-intercept is 2
