Sample WVGSA Grade 8 Math Practice Questions

Try these sample questions to review concepts for the WVGSA Grade 8 Math exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the simplified value of \(\frac{4^7}{4^4}\)?
A.12
B.64
C.256
D.1024
Explanation: According to the quotient rule for exponents, \(a^m / a^n = a^{m-n}\). Therefore, \(\frac{4^7}{4^4} = 4^{7-4} = 4^3 = 64\).
2Which expression is equivalent to \(5^{-3}\)?
A.-15
B.-125
C.\(\frac{1}{125}\)
D.\(\frac{1}{15}\)
Explanation: By the definition of negative exponents, \(a^{-n} = \frac{1}{a^n}\). Thus, \(5^{-3} = \frac{1}{5^3} = \frac{1}{125}\).
3What is the number 0.00048 written in scientific notation?
A.\(4.8 \times 10^{-5}\)
B.\(4.8 \times 10^{-4}\)
C.\(4.8 \times 10^4\)
D.\(48 \times 10^{-5}\)
Explanation: To express 0.00048 in scientific notation, move the decimal point 4 places to the right to obtain a coefficient of 4.8 between 1 and 10. Since the decimal moved right, the exponent of 10 is negative, yielding \(4.8 \times 10^{-4}\).
4Solve for \(x\): \(x^2 = 121\).
A.11
B.22
C.60.5
D.242
Explanation: Taking the square root of both sides gives \(x = \sqrt{121} = 11\) (or -11). Because 11 squared equals 121, 11 is the positive solution.
5Solve for \(y\): \(y^3 = 64\).
A.4
B.8
C.16
D.21.33
Explanation: Taking the cube root of both sides gives \(y = \sqrt[3]{64} = 4\), because \(4 \times 4 \times 4 = 64\).
6A linear graph representing a proportional relationship passes through the origin \((0,0)\) and the point \((4, 12)\). What is the unit rate (slope) of this relationship?
A.\(\frac{1}{3}\)
B.3
C.8
D.48
Explanation: The unit rate or slope \(m\) is calculated using \(m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 0}{4 - 0} = \frac{12}{4} = 3\).
7Solve for \(x\): \(3x + 8 = 29\).
A.5
B.7
C.11
D.37
Explanation: Subtract 8 from both sides to get \(3x = 21\). Divide both sides by 3 to find \(x = 7\).
8What are the slope and \(y\)-intercept of the linear equation \(y = -2x + 7\)?
A.Slope = 7, y-intercept = (0, -2)
B.Slope = -2, y-intercept = (0, 7)
C.Slope = 2, y-intercept = (0, -7)
D.Slope = -2, y-intercept = (0, -7)
Explanation: In slope-intercept form \(y = mx + b\), \(m\) is the slope and \(b\) is the \(y\)-intercept. Here \(m = -2\) and \(b = 7\), so the \(y\)-intercept point is \((0, 7)\).
9Which set of ordered pairs represents a function?
A.\(\{(1, 2), (2, 4), (3, 6), (4, 8)\}\)
B.\(\{(2, 3), (2, 5), (4, 7), (5, 9)\}\)
C.\(\{(3, 1), (3, 4), (3, 7), (3, 9)\}\)
D.\(\{(5, 2), (5, 8), (6, 1), (7, 3)\}\)
Explanation: A relation is a function if every input (\(x\)-value) is mapped to exactly one output (\(y\)-value). In the set \(\{(1, 2), (2, 4), (3, 6), (4, 8)\}\), all \(x\)-values (1, 2, 3, 4) are unique, so no input is paired with two different outputs.
10Which equation represents a linear function?
A.\(y = x^2 + 3\)
B.\(y = 4x - 5\)
C.\(y = \frac{2}{x}\)
D.\(y = 3^x\)
Explanation: A linear function can be written in the form \(y = mx + b\), where the variable \(x\) has an exponent of 1. Equation \(y = 4x - 5\) fits this linear form.
