Replace y by f(x), which BTW does NOT mean "f times x"
as you were taught earlier.
f(x) = 7x - 11
"f(x)" means this:
If you substitute a number for x in "f(x)" and also for x in
the right side of the equation that defines f(x) and simplify,
you will get the y-coordinate of the ordered pair that has
that number as its x-coordinate which is a solution.
For instance
f(2) = 7(2) - 1
f(2) = 14 - 1
f(2) = 13
So the ordered pair (2,13) is a solution to
f(x) = 7x - 1
