| (A) |
B) Yes it shows a linear relation because it goes over and up in the same pattern every time
C) It wouldn't work to have points in between because in order to get Y(p) you need to multiply (x) by 9. (9x=y)
A) The graph is about a Grade 8 car wash. It includes the number of cars and the income for how many cars washed.
B) The pattern on this graph is over 1 and up 10
C) The cost of 1 car wash is 10 dollars

C) 3x+2=y/ 3(2)+2=y/ 6+2=y/ 8=y
The value of y when x=2 is 8
D) 3x+2=y/ 3(5)+2=y/ 15+2=y/ 17=y
The value of y when x=5 is 17
