Answer:

A = 13 B =0 = 1/2   This way x in a graph can be his start running ability (time) each A value applied will divide by 1/2 to make 6.5 and when x = 21 then y can be 7 with the AB equation above as 13 x 1/2 = 6.5. add multiple 0 doesn't occur because we start with x value 21 to show the starting value. Alternately x= 137 and y = 0. Then the graph can go up or down when his running value changes as a negative decrease 137 - b = -? and a positive increase will show increase 137+b = +?.

Step-by-step explanation:
