Question

which equation in point slope form correctly represents zadas pay in dollars, y, when she works x hours?

Answer 1

The correct answer is A

`y-68=2(x-4)`

Step-by-step explanation

We were told that Zada is paid at an hourly rate of $
`12` per hour.

The unit rate of payment represents the slope of the straight line graph that models Zada's earnings. Thus
`m=12`

When she works for 4 hours she earns a total of $68 tells us that the point,
`(4,68)` lies on the model straight line.

Using the formula for the point slope form

`y-y_1=m(x-x_1)`

we obtain the equation as follows.

`y-68=2(x-4)`
