Please help me! ƒ(x) = -x + 3 (show work)

Step-by-step explanation:

In this equation, x is -1, so the parts where x is, substitute those with -1

f(-1)=-1+3

f(x)=2

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
