9. Sue earned $120 for 15 hours of work. Which equation represents the relationship between the hours worked, x, and Sue's pay y
A y = 8x
By= 18x
C y = 120x
Dy = 9x

 C = 120x

Have a nice day:

9514 1404 393

  A  y = 8x

Step-by-step explanation:

We are given that y = 120 when x = 15, and we assume that pay is proportional to hours worked. That is ...

  y = kx

  k = y/x = 120/15 = 8

So, the relation between hours worked (x) and Sue's pay (y) is ...

  y = 8x

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
