Linear Functions
What is the slope between the points (-9, 5) and (-10, -9)?
- 16
- 14 ✓
- 15
- 13
Why: m = (y₂ − y₁)/(x₂ − x₁) = (-14)/(-1) = 14.
Find the slope of the line through (6, 6) and (8, -6).
- -6 ✓
- -7
- -5
- -4
Why: m = (y₂ − y₁)/(x₂ − x₁) = (-12)/(2) = -6.
What is the slope between the points (9, -6) and (10, 13)?
- 18
- 20
- 19 ✓
- 21
Why: m = (y₂ − y₁)/(x₂ − x₁) = (19)/(1) = 19.
Write the equation of the line through (-3, -1) and (-2, -1) in slope-intercept form. What is the y-intercept b?
- 0
- 1
- -1 ✓
- -2
Why: Slope m = 0. Use y = mx + b: -1 = 0(-3) + b → b = -1 = -1.
Write the equation of the line through (7, -7) and (5, 1) in slope-intercept form. What is the y-intercept b?
- 21 ✓
- 22
- 20
- 23
Why: Slope m = -4. Use y = mx + b: -7 = -4(7) + b → b = 21 = 21.
Linear Equations, Inequalities & Systems
Solve for x: 3x + 14 = 7x + 38
- -6 ✓
- -5
- -7
- -4
Why: 3x − 7x = 38 − 14 → -4x = 24 → x = -6.
Solve for x: 7x − 1 = 4x − 7
- -2 ✓
- 0
- -3
- -1
Why: 7x − 4x = -7 − -1 → 3x = -6 → x = -2.
Which value of x satisfies the inequality? 6x − 2 > 16
- 4 ✓
- 2
- 1
- 3
Why: Solve: 6x > 18 → x > 3. 4 works.
Solve the system by substitution: y = 3x + 12 4x + 1y = -37 Find x.
- -6
- -5
- -8
- -7 ✓
Why: Substitute y = 3x + 12 into 4x + 1y = -37, solve to get x = -7, y = -9.
Solve the system by elimination: 4x + 2y = 30 4x + 4y = 44 Find y.
- 8
- 6
- 9
- 7 ✓
Why: Multiply rows to eliminate one variable, then solve. Solution: x = 4, y = 7.
Exponents & Polynomials
Simplify: (x^6)^2. What is the exponent of x?
- 13
- 14
- 11
- 12 ✓
Why: When raising a power to a power, multiply exponents: 6 × 2 = 12.
Expand (x − 4)(x + 9). What is the coefficient of x in the expanded form?
- 6
- 7
- 5 ✓
- 4
Why: Use FOIL: x·x + x·9 + -4·x + -4·9 = x² + 5x + -36. The coefficient of x is 5.
Expand (x + 2)(x − 4). What is the coefficient of x in the expanded form?
- -2 ✓
- -1
- -3
- 0
Why: Use FOIL: x·x + x·-4 + 2·x + 2·-4 = x² + -2x + -8. The coefficient of x is -2.
Expand (x + 9)(x + 4). What is the coefficient of x in the expanded form?
- 12
- 15
- 14
- 13 ✓
Why: Use FOIL: x·x + x·4 + 9·x + 9·4 = x² + 13x + 36. The coefficient of x is 13.
Factor: x² + 9x + 18
- (x − 3)(x − 6)
- (x − 3)(x + 6)
- (x + 3)(x + 6) ✓
- (x + 3)(x − 6)
Why: Find two numbers whose product is 18 and sum is 9: 3 and 6. So x² + 9x + 18 = (x + 3)(x + 6).
Quadratic Functions & Equations
Solve by factoring: x² + 0x − 64 = 0
- x = -7, x = 9
- x = -8, x = 8 ✓
- x = 8, x = -8
- x = -9, x = 7
Why: Factors as (x + -8)(x + 8) = 0, so x = 8 or x = -8.

- x = -3, x = 6
- x = 2, x = -7

- x = -2, x = 1
- x = 1, x = -2
- x = -1, x = 2 ✓

- 126
- 125 ✓
- 127
- 124
Why: f(3) = 1 · 5^3 = 1 · 125 = 125.
Is f(x) = 378 · (1.06)^x exponential growth or decay?
- Growth ✓
- Neither
- Decay
- Linear
Why: Since the base 1.06 > 1, the function shows exponential growth.
