ANSWER
The correct answer is A
[tex]y-68=2(x-4)[/tex]
EXPLANATION
We were told that Zada is paid at an hourly rate of $[tex]12[/tex] per hour.
The unit rate of payment represents the slope of the straight line graph that models Zada's earnings. Thus [tex]m=12[/tex]
When she works for 4 hours she earns a total of $68 tells us that the point,[tex](4,68)[/tex] lies on the model straight line.
Using the formula for the point slope form
[tex]y-y_1=m(x-x_1)[/tex]
we obtain the equation as follows.
[tex]y-68=2(x-4)[/tex]
