Relating linear contexts to graph features?
Apolline is mowing lawns for a summer job. For every mowing job, she charges an initial fee plus a constant fee for each hour of work. Her fee for a 5-hour job, for instance, is $42. Her fee for a 3 - hour job is $28.
Let y represent Anumeha's fee (in dollars) for a single job that took x hours for her to complete.
Which of the following information about the graph of the relationship is given?
A. Slope and x - intercept
B. Slope and y - intercept
C. Slope and a point that is not an intercept
D. x - intercept and y - intercept
E. y - intercept and a point that is not an intercept
F. Two points that are not intercepts
My answer is F. Two points that are not intercepts
I'm I right? If not, please provide correct answer..

Yes of course you are right
Let's find out the slope and y-intercept
2 hours of work brings an additional $14
Slope = 7 $/h
If we extrapolate from the (3, 28) we get for 0 hours of work 28 - 3*7 = 7 dollars
y = 7 + 7x
