Question 1 of 10
Michigan Standards 5A-5CMedium Calc Word Diagram
The graph shows two lines. What is the solution to the system? xyy=x+1y=-x+3(1, 2)
A(0, 1)
B(1, 2)
C(3, 0)
D(2, 3)
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
Michigan Standards 4A-4CEasy Calc Word Diagram
What type of correlation does this scatter plot show? xy
APositive
BNegative
CPerfect
DNo correlation
Explanation
📌 Points trend downward from left to right → negative correlation.
As x increases, y decreases.
Question 3 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? Hours StudiedTest Score
ACannot determine
BPositive correlation
CNo correlation
DNegative 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.
Question 4 of 10
Michigan Standards 2A-2HEasy Calc Word Diagram
What is the slope of the line shown? xy(-2,-1)(2,3)run = 4rise = 4
A1
B−1
C1/2
D2
Explanation
📌 slope = rise/run = (3-(-1))/(2-(-2)) = 4/4 = 1

💡 Positive slope → line goes UP from left to right.
Question 5 of 10
Michigan Standards 2A-2HMedium Calc Word Diagram
Which line has a negative slope? A ↗B ↘
ABoth
BB
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 6 of 10
Michigan Standards 3A-3GEasy Calc Word Diagram
Which graph represents y = 2x + 1? AB
ABoth
BB
CA
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 7 of 10
Michigan Standards 12A-12EEasy Calc Word
If f(x) = 2x + 5, what is f(3)?
A13
B16
C8
D11
Explanation
📌 f(3) = 2(3) + 5 = 6 + 5 = 11
Function notation: replace x with 3.
Question 8 of 10
Michigan Standards 12A-12EEasy Calc Word
What is the 10th term of the arithmetic sequence: 3, 7, 11, 15, ...?
A43
B37
C35
D39
Explanation
📌 Common difference d = 7 − 3 = 4
a_n = a_1 + (n−1)d = 3 + (10−1)(4) = 3 + 36 = 39
Question 9 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? Monthly Plan$30+ $0.10/textC = ?t = number of texts
AC = 30 + 0.10t
BC = 30t + 0.10
CC = 0.10(30 + t)
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 10 of 10
Michigan Standards 5A-5CMedium Calc Word Diagram
The system of equations is graphed below. How many solutions does it have? Line 1Line 2Parallel — no intersection
AOne solution
BInfinitely many solutions
CTwo solutions
DNo solution
Explanation
📌 The lines are parallel (same slope, different y-intercepts).
Parallel lines NEVER intersect → NO solution.

Systems with no solution are called 'inconsistent.'
