As the ball bounces, the height lowers due to gravity, Goes down by 50, 40, 32, 26.6. It should continue to go down.
(If im wrong ill edit the answer.)
This equation forms a linear line so the graph is going to be linear.
this equation in slope intercept form.
C=2 and j=4
j+y=2(c+y)-7
j+y=2c+2y-7 and since j=4 and c=2 we have:
4+y=2*2+2y-7
y+4=2y+4-7
y+4=2y-3
-y+4=-3
-y=-7
y=7
So in 7 years Jenny will be 7 years younger than twice Chris' age.
check...
4+7=2(2+7)-7
11=2(9)-7
11=18-7
11=11
