Substitute 3 for x in 

Evaluate all exponents



A) 7.5/3=2.5
b) So about 3 pieces can be cut.
F(x)= 2x-3
f(0)=2•0-3=0-3=-3 ✔️
f(7)=2•7-3=14-3=11 ✔️
156 ft. Multiply 13 by 12, there is 1 inch= 13 ft
The slope is m = 2
“M” means slope
When you see a number in front of “x” that’s the slope in that case.
