Question 1 of 10
TEKS 1A-1GEasy Calc Word Diagram
A cell phone plan charges $30 per month plus $0.10 per text. Which equation represents the monthly cost C for t texts? Monthly Phone PlanBase: $30 per monthEach text: $0.10
AC = 30 + 0.10t
BC = 0.10(30 + t)
CC = 30t + 0.10
DC = 30.10t
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.
Question 2 of 10
TEKS 3A-3GEasy Calc Word Diagram
Which graph represents y = 2x + 1? AB
AB
BA
CBoth
DNeither
Explanation
📌 y = 2x + 1:
• Slope = 2 (positive → goes UP)
• y-intercept = 1 (crosses y-axis above origin)
Graph A shows positive slope with y-intercept above origin.
Question 3 of 10
TEKS 4A-4CMedium Calc Word Diagram
The scatter plot shows the relationship between hours studied and test scores. What type of correlation is shown? Hours StudiedTest Score
ANo correlation
BPositive correlation
CNegative correlation
DCannot determine
Explanation
📌 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 of 10
TEKS 2A-2HEasy Calc Word Diagram
What is the slope of the line shown? -6-4-2246-6-4-2246O
A2
B−1
C1
D1/2
Explanation
📌 slope = rise/run = (3-(-1))/(2-(-2)) = 4/4 = 1

💡 Positive slope → line goes UP from left to right.
Question 5 of 10
TEKS 1A-1GMedium Calc Word
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?
A200
B350
C250
D300
Explanation
📌 70 = 25 + 0.15m
45 = 0.15m
m = 300 miles
Question 6 of 10
TEKS 2A-2HMedium Calc Word Diagram
Which line has a negative slope? AB
AB
BBoth
CNeither
DA
Explanation
📌 Negative slope = line goes DOWN from left to right (↘).
Positive slope = line goes UP from left to right (↗).
Graph B has negative slope.
Question 7 of 10
TEKS 5A-5CMedium Calc Word Diagram
The graph shows two lines. What is the solution to the system? -6-4-2246-6-4-2246O
A(3, 0)
B(1, 2)
C(2, 3)
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 ✓
Question 8 of 10
TEKS 5A-5CMedium Calc Word Diagram
The system of equations is graphed below. How many solutions does it have? -6-4-2246-6-4-2246O
AOne solution
BNo solution
CTwo solutions
DInfinitely many solutions
Explanation
📌 The lines are parallel (same slope, different y-intercepts).
Parallel lines NEVER intersect → NO solution.

Systems with no solution are called 'inconsistent.'
Question 9 of 10
TEKS 5A-5CHard Calc
Solve: 3x+4y=10, 2x−4y=−5
A(0, 2.5)
B(1, 2)
C(1, 1.75)
D(2, 1)
Explanation
📌 Add: 5x=5 → x=1. 3(1)+4y=10 → 4y=7 → y=7/4=1.75
Question 10 of 10
TEKS 5A-5CHard Calc Word
Solve: 2x + 3y = 13, 4x − y = 5
A(2, 3)
B(1, 4)
C(4, 1)
D(3, 2)
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
