$7.22 would be the answer because 70% of 10.31 is what you are looking for which is 7.217 which is rounded to 7.22 I know this is right because I just learned this and I am in advanced math 6th grade.

Step-by-step explanation:
Answer:
slope of line is 3/5
Step-by-step explanation:
slope is the ratio of the change in the y-values over the change in the x-values
in this problem, if you go from pt A to pt B, you rise by 3 and go to the right by 5, thus slope of 3/5
if you go from pt B to pt C, you rise by 6 and go to the right by 10
however, 6/10 can be reduced to 3/5
if you start at point (0,2) and rise by 3 and run to the right by 5 you are at point (5,5)
change in y-values is 5-2 or 3
change in x-values is 5-0 or 5
(5-2)/(5-0) = 3/5
2X-2=2X+9
Add 2
2X=2X+11
Subract 2X
0= 11
This has no solution to this problem
