To graph the equation, plot a few points then connect then with a line.
f(x) = 440 - 55x
Plug in numbers for x to get the y value.
f(0) = 440
f(1) = 385
f(2) = 330
f(3) = 275
f(4) = 220
f(5) = 165
So when you graph these points, the y intercept is y = 440 because the graph crosses the y axis at (0, 440).
The x intercept is where the graph crosses the x axis. This happens when y = 0.
0 = 440 - 55x. Solve for x.
55x = 440
x = 8
So the x intercept is x = 8
Nancy would have because she saved 2 each week and had a total of 4 dollars and Marco saved 1 dollar the first week and saved 2 dollars the second week and had a total of 3 dollars so Nancy had 1 dollar more than Marco

Answer = 5 problems per minute
Because you do the number of problems divided by the minutes eg 35/7 = 5
