Practice questions with answers
Question 1
A cell phone plan charges $30 per month plus $0.10 per text. Which equation represents the monthly cost C for t texts?
A. C = 30t + 0.10
B. C = 30 + 0.10t
C. C = 0.10(30 + t)
D. C = 30.10t
Show the answer and explanation
Correct answer: B. C = 30 + 0.10t
📌 Fixed cost = $30 (base monthly charge) Variable cost = $0.10 per text = 0.10t Total: C = 30 + 0.10t 💡 This is a linear equation in slope-intercept form: y = mx + b where m = 0.10 and b = 30.
Question 2
What is the slope of the line shown?
A. −1
B. 1
C. 2
D. 1/2
Show the answer and explanation
Correct answer: B. 1
📌 slope = rise/run = (2-(-2))/(2-(-2)) = 4/4 = 1 💡 Positive slope → line goes UP from left to right.
Question 3
The scatter plot shows the relationship between hours studied and test scores. What type of correlation is shown?
A. Negative correlation
B. Positive correlation
C. No correlation
D. Cannot determine
Show the answer and explanation
Correct answer: B. Positive correlation
📌 Points trend upward from left to right → positive correlation. As hours studied increases, test score increases. The trend line slopes upward → positive relationship.
Question 4
Which line has a negative slope?
A. A
B. B
C. Both
D. Neither
Show the answer and explanation
Correct answer: B. B
📌 Negative slope = line goes DOWN from left to right (↘). Positive slope = line goes UP from left to right (↗). Graph B has negative slope.
Question 5
Which graph represents a quadratic function?
A. A
B. B
C. Both
D. Neither
Show the answer and explanation
Correct answer: A. A
📌 Quadratic = U-shaped parabola. Graph A shows a parabola. Graph B is a straight line → linear, not quadratic.
Question 6
The parabola in the graph below has a vertex at which point?
A. (1, -2)
B. (-1, 2)
C. (0, 0)
D. (2, 1)
Show the answer and explanation
Correct answer: A. (1, -2)
The vertex is the lowest point of an upward-opening parabola, marked at approximately (1, -2).
Question 7
The graph shows two lines. What is the solution to the system?
A. (0, 1)
B. (1, 2)
C. (2, 3)
D. (3, 0)
Show the answer and explanation
Correct answer: B. (1, 2)
📌 The solution is where the lines intersect = (1, 2). Verify: y = x + 1 → 2 = 1 + 1 ✓ y = −x + 3 → 2 = −1 + 3 ✓
Question 8
The system of equations is graphed below. How many solutions does it have?
A. One solution
B. No solution
C. Infinitely many solutions
D. Two solutions
Show the answer and explanation
Correct answer: B. No solution
📌 The lines are parallel (same slope, different y-intercepts). Parallel lines NEVER intersect → NO solution. Systems with no solution are called 'inconsistent.'
Question 9
A ball is thrown upward. Its height is h = −16t² + 48t. When does it hit the ground?
A. 1 sec
B. 2 sec
C. 3 sec
D. 4 sec
Show the answer and explanation
Correct answer: C. 3 sec
📌 h = 0: −16t² + 48t = 0 → t(−16t + 48) = 0 → t = 0 or t = 3 seconds
