Hard
9. Solve: 2(3x - 5) = 4x + 18
Hard
10. A line has slope -2 and passes through (4,7). Find intercept form.
Answer key preview
1. x = 12
Subtract 7 from both sides.
2. 11
f(3) = 2(3) + 5 = 11.
3. 2
(6 - 2)/(3 - 1) = 4/2 = 2.
4. 6x - 12
Distribute 3 to both terms.
Common student mistakes
- Confusing slope with y-intercept
- Using additive patterns for multiplicative function rules
- Sign errors while combining like terms
- Forgetting to square both legs in Pythagorean work
- Misreading scientific notation exponents
When to use this test
Use Grade 8 tests for pre-Algebra readiness checks, end-of-unit review, and mid-year benchmark cycles. Because the test is short and balanced, it fits both class periods and intervention blocks.
For retakes and make-up exams, generate A/B versions to keep domain alignment while reducing direct item overlap.
