A car rental costs $25 per day plus $0.15 per mile. If the total cost is $70 for one day, how many miles were driven?
A300
B250
C200
D350
Explanation
📌 70 = 25 + 0.15m 45 = 0.15m m = 300 miles

Solve: 3x+4y=10, 2x−4y=−5
A(1, 1.75)
B(1, 2)
C(2, 1)
D(0, 2.5)
Explanation
📌 Add: 5x=5 → x=1. 3(1)+4y=10 → 4y=7 → y=7/4=1.75

The graph shows two lines. What is the solution to the system?
A(1, 2)
B(2, 3)
C(3, 0)
D(0, 1)
Explanation
📌 The solution is where the lines intersect = (1, 2). Verify: y = x + 1 → 2 = 1 + 1 ✓ y = −x + 3 → 2 = −1 + 3 ✓

The scatter plot shows the relationship between hours studied and test scores. What type of correlation is shown?
ACannot determine
BNegative correlation
CPositive correlation
DNo correlation
Explanation
📌 Points trend upward from left to right → positive correlation. As hours studied increases, test score increases. The trend line slopes upward → positive relationship.

Which line has a negative slope?
AA
BBoth
CB
DNeither
Explanation
📌 Negative slope = line goes DOWN from left to right (↘). Positive slope = line goes UP from left to right (↗). Graph B has negative slope.

Solve: 2x + 3y = 13, 4x − y = 5
A(2, 3)
B(1, 4)
C(3, 2)
D(4, 1)
Explanation
📌 From eq2: y = 4x − 5 Substitute: 2x + 3(4x−5) = 13 → 2x + 12x − 15 = 13 → 14x = 28 → x = 2 y = 4(2) − 5 = 3

The system of equations is graphed below. How many solutions does it have?
ANo solution
BOne solution
CInfinitely many solutions
DTwo solutions
Explanation
📌 The lines are parallel (same slope, different y-intercepts). Parallel lines NEVER intersect → NO solution.
Systems with no solution are called 'inconsistent.'

A cell phone plan charges $30 per month plus $0.10 per text. Which equation represents the monthly cost C for t texts?
AC = 0.10(30 + t)
BC = 30 + 0.10t
CC = 30.10t
DC = 30t + 0.10
Explanation
📌 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.
