1. If f(x) = 2x + 3, find f(5)
2. Find the slope between (1, 2) and (4, 11)
3. Write the equation of a line with slope 4 and y-intercept −1
Preview shows representative problems from the printable student-facing PDF.
Answer key preview
1. 13
f(5) = 2(5) + 3 = 10 + 3 = 13
2. 3
(11 − 2) ÷ (4 − 1) = 9 ÷ 3 = 3
3. y = 4x − 1
Use y = mx + b form
Worked answers help teachers verify explanation depth, not just final-answer accuracy.
