Below are sample questions representative of the exercises included on this worksheet and related ALG1.138 Mixed Practice and Test Readiness Sets Answer Key skill assessments:

Problem 1Difficulty: Mastery
After solving a linear equation in a mixed set, the next item shows a scatter plot with a trend line and asks for a prediction. What action best shows test readiness?
AKeep solving for x because the previous item was an equation
BIgnore the graph and choose the largest answer
CFactor the trend line before reading it
DReset the strategy by identifying the new item as data modeling, then use the trend line for prediction
Solution & Explanation:Mixed practice tests whether students can switch strategies. A scatter plot with a trend line is a data-modeling prompt, not another equation-solving prompt.
Problem 2Difficulty: Mastery
A prompt says: Which transformation keeps the solution set of 6x - 9 = 21 unchanged? Which target skill is most precise?
AScatter-plot association based on a line of fit
BHistogram frequency based on interval width
CEquivalent equations created by applying the same valid operation to both sides
DQuadratic graphing based on the vertex
Solution & Explanation:Keeping the same solution set means the equation must be transformed by valid operations on both sides, such as adding 9 to both sides or dividing both sides by 3.
Problem 3Difficulty: Mastery
Which prompt is targeting systems of equations rather than only slope?
AFind the slope of the line through (1, 4) and (3, 10)
BFind the point where y = 2x + 3 and y = -x + 12 intersect
CDecide whether a scatter plot has positive association
DFind the median of 6, 8, 10, 12, 14
Solution & Explanation:An intersection of two lines asks for the ordered pair satisfying both equations, which is a systems skill. A slope-only question usually has one line or two points.
