Best ResponseYou've already chosen the best response.1no it is not a linear "function" it is an equation for a line thus beginning the long confusion between the concept of "function" and "equation" it is not your fault just bad math teachers

Best ResponseYou've already chosen the best response.1anyway what they want you to do is solve for \(y\) \[y  2 = x + 1\] \[y=x+3\] \[y=x3\]

Best ResponseYou've already chosen the best response.1and then say "since the slope is negative, it is decreasing

Best ResponseYou've already chosen the best response.1\[y=x3\\y=mx+b\] \[m=1\] so it is decreasing
