Sample New Mexico NM-MSSA Math Grade 8 Practice Questions

Try these sample questions to test your New Mexico NM-MSSA Math Grade 8 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A function is defined by the rule y = 3x - 4. What is the output when the input is 5?

A.11

B.19

C.8

D.15

Explanation: Substitute x = 5: y = 3(5) - 4 = 15 - 4 = 11.

2Which set of ordered pairs does NOT represent a function?

A.{(1,2),(2,4),(3,6)}

B.{(1,2),(1,3),(2,4)}

C.{(0,0),(1,1),(2,2)}

D.{(-1,1),(0,0),(1,1)}

Explanation: In a function, each input maps to exactly one output. In {(1,2),(1,3),(2,4)}, the input 1 maps to both 2 and 3, so it is not a function.

3A relation maps each input to exactly one output. Which statement must be true?

A.Every input has exactly one output

B.Every output has exactly one input

C.Inputs can have multiple outputs

D.Outputs must equal inputs

Explanation: The defining property of a function is that every input is assigned exactly one output.

4Which equation represents a nonlinear function?

A.y = 2x + 3

B.y = -4x

C.y = x^2 + 1

D.y = (1/2)x - 7

Explanation: y = x^2 + 1 is nonlinear because the variable x has an exponent of 2, so the rate of change is not constant.

5What is the slope of the linear function y = 4x - 7?

A.4

B.-7

C.7

D.-4

Explanation: In y = mx + b, m is the slope. Here m = 4, so the slope is 4.

6What is the y-intercept of the line y = -2x + 6?

A.6

B.-2

C.2

D.-6

Explanation: In y = mx + b, b is the y-intercept. Here b = 6, so the y-intercept is 6.

7A linear function has the table x: 0, 1, 2, 3 and y: 3, 7, 11, 15. What is the rate of change?

A.4

B.3

C.7

D.12

Explanation: The rate of change is the change in y divided by the change in x: (7 - 3)/(1 - 0) = 4/1 = 4.

8Using the table x: 0, 1, 2, 3 and y: 3, 7, 11, 15, what is the initial value of the function?

A.3

B.4

C.0

D.7

Explanation: The initial value is the output when the input is 0. When x = 0, y = 3, so the initial value is 3.

9A table has x: 1, 2, 3, 4 and y: 2, 5, 8, 11. Is the function linear, and why?

A.Yes, the rate of change is constant at 3

B.No, the y-values are not constant

C.Yes, the rate of change is 11

D.No, x increases by 1 each time

Explanation: The rate of change is (5-2)/(2-1) = 3, (8-5)/(3-2) = 3, and (11-8)/(4-3) = 3. Since the rate is constant, the function is linear.

10A linear function passes through (0, 2) and has a rate of change of 3. Which equation represents the function?

A.y = 3x + 2

B.y = 2x + 3

C.y = 3x - 2

D.y = -3x + 2

Explanation: With rate of change (slope) m = 3 and initial value (y-intercept) b = 2, the equation is y = 3x + 2.

New Mexico NM-MSSA Math Grade 8 Study Tips from Top Performers

1Check whether an equation has one solution, no solution, or infinitely many by simplifying both sides first.

2Tell linear from nonlinear functions by checking for a constant rate of change.

3Use the Pythagorean theorem (a² + b² = c²) only on right triangles, with c as the hypotenuse.

4Convert scientific notation by moving the decimal the same number of places as the exponent.

5Fit a line of best fit to a scatter plot by drawing a straight line that follows the trend of the points.
