Sample AK STAR Math Grade 9 Practice Questions

Try these sample questions to review concepts for the AK STAR Math Grade 9 exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 109+ question experience with AI tutoring.

1If f(x) = 3x − 5, what is f(4)?

A.7

B.12

C.17

D.−1

Explanation: Substitute x = 4: f(4) = 3(4) − 5 = 12 − 5 = 7. Function notation f(4) means evaluate the rule at input 4.

2If g(x) = −2x + 9, what is g(−3)?

A.15

B.3

C.−15

D.6

Explanation: g(−3) = −2(−3) + 9 = 6 + 9 = 15. The product −2 · (−3) is positive 6 before adding 9.

3Which ordered pair is on the graph of y = 2x + 1?

A.(3, 7)

B.(2, 3)

C.(1, 1)

D.(0, 2)

Explanation: For (3, 7): 2(3) + 1 = 7, so the point satisfies the equation and lies on the line.

4What is the slope of the linear function f(x) = −4x + 11?

A.−4

B.11

C.4

D.−11

Explanation: In slope-intercept form f(x) = mx + b, the coefficient m is the slope. Here m = −4.

5What is the y-intercept of f(x) = (1/2)x − 6?

A.−6

B.1/2

C.6

D.−1/2

Explanation: The y-intercept is f(0) = −6. In slope-intercept form, the constant term b = −6 is the y-intercept.

6A linear function has slope 3 and passes through (0, −2). Which equation represents the function?

A.f(x) = 3x − 2

B.f(x) = −2x + 3

C.f(x) = 3x + 2

D.f(x) = 2x − 3

Explanation: Slope-intercept form is f(x) = mx + b. With m = 3 and y-intercept −2, the equation is f(x) = 3x − 2.

7A table shows a linear function: when x = 0, f(x) = 5; when x = 1, f(x) = 8; when x = 2, f(x) = 11. Which equation matches the table?

A.f(x) = 3x + 5

B.f(x) = 5x + 3

C.f(x) = 3x − 5

D.f(x) = x + 5

Explanation: Each 1-unit increase in x raises f(x) by 3, so the slope is 3. When x = 0, f(x) = 5, so f(x) = 3x + 5.

8If f(x) = 5 − x and g(x) = 2x + 1, what is f(3) + g(3)?

A.9

B.2

C.7

D.4

Explanation: f(3) = 5 − 3 = 2 and g(3) = 2(3) + 1 = 7. Adding gives 2 + 7 = 9.

9Which description matches a linear function with a constant rate of change of −2?

A.As x increases by 1, y decreases by 2

B.As x increases by 1, y increases by 2

C.As x doubles, y doubles

D.As x increases by 1, y is multiplied by −2

Explanation: A constant rate of change of −2 means the output decreases by 2 for each 1-unit increase in the input—the definition of slope −2.

10A taxi charges a $3 base fee plus $2 per mile. Which function models the cost C in dollars for m miles?

A.C(m) = 2m + 3

B.C(m) = 3m + 2

C.C(m) = 2m − 3

D.C(m) = 5m

Explanation: The base fee is the constant 3 and the rate $2 per mile is the slope, so C(m) = 2m + 3.

AK STAR Math Grade 9: Suggested Study Strategy

1Practice multi-step word problems that require choosing operations carefully.

2Build fluency on grade-level computation before relying on calculators (especially grades 3–5, where calculators are not allowed).

3Explain answers with models, equations, and units—not only final numbers.

4Use DEED formula sheets for grades that provide them and official practice tests for item types.

5Review mistakes by identifying whether the error was computation, concept, or misread wording.
