Question 1 of 10

Michigan Standards 5A-5CMedium Calc Word Diagram

The graph shows two lines. What is the solution to the system?

A(2, 3)

B(0, 1)

C(1, 2)

D(3, 0)

Explanation

📌 The solution is where the lines intersect = (1, 2).
Verify: y = x + 1 → 2 = 1 + 1 ✓
y = −x + 3 → 2 = −1 + 3 ✓

Question 2 of 10

The system of equations is graphed below. How many solutions does it have?

ATwo solutions

BOne solution

CNo solution

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 3 of 10

What type of correlation does this scatter plot show?

ANegative

BPerfect

CNo correlation

DPositive

Explanation

📌 Points trend downward from left to right → negative correlation.
As x increases, y decreases.

Question 4 of 10

Michigan Standards 4A-4CMedium Calc Word Diagram

The scatter plot shows the relationship between hours studied and test scores. What type of correlation is shown?

APositive correlation

BNegative correlation

CNo 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 5 of 10

Michigan Standards 3A-3GEasy Calc Word Diagram

Which graph represents y = 2x + 1?

CNeither

DBoth

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 6 of 10

Michigan Standards 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?

AC = 30.10t

BC = 30t + 0.10

CC = 30 + 0.10t

DC = 0.10(30 + t)

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 7 of 10

Michigan Standards 12A-12EEasy Calc Word

If f(x) = 2x + 5, what is f(3)?

A16

B11

C13

Explanation

📌 f(3) = 2(3) + 5 = 6 + 5 = 11
Function notation: replace x with 3.

Question 8 of 10

Michigan Standards 2A-2HEasy Calc Word Diagram

What is the slope of the line shown?

A−1

C1/2

Explanation

📌 slope = rise/run = (3-(-1))/(2-(-2)) = 4/4 = 1

💡 Positive slope → line goes UP from left to right.

Question 9 of 10

Michigan Standards 12A-12EEasy Calc Word

What is the 10th term of the arithmetic sequence: 3, 7, 11, 15, ...?

A37

B35

C43

D39

Explanation

📌 Common difference d = 7 − 3 = 4
a_n = a_1 + (n−1)d = 3 + (10−1)(4) = 3 + 36 = 39

Question 10 of 10

Michigan Standards 2A-2HMedium Calc Word Diagram

Which line has a negative slope?

CBoth

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.
