Jabian buys pencils as souvenirs from his vacation to give to his friends. He starts with 90 pencils and gives away 15 each hour
until he has no pencils left. Use the Segment tool to plot a graph representing the number of pencils Jabian has left to give away from the time he starts giving them away until he has no pencils left.
The slope is the rise (up) over run (left or right depending on if the number is negative) between points. So the next point on the graph is up 5 and over 10. this simplified is 1/2. Then you put this into y=mx which is y=1/2x
