MO MAP Grades 6-8 Functions. Practice it free.

In grades 6-8, function work begins with variables and tables and becomes formal in Grade 8. This Grades 6-8 reporting domain maps to 6 practice skills and 8 representative questions from the playable bank.

Grades 6-86 mapped skills
What the test measures

Functions skills

  1. Grade 6: represent and analyze quantitative relationships between dependent and independent variables

  2. Grade 7: graph proportional relationships and analyze rate of change

  3. Grade 8: define, evaluate, and compare functions; use functions to model relationships

Standards basis

Missouri Learning Standards (Mathematics K-5 and Mathematics 6-12; revised standards approved April 19, 2016) — Missouri

How the MO MAP reports it

Missouri’s MAP math is built from the Missouri Learning Standards and the state’s item specifications, not from a separate national testing framework. The standards are closely CCSS-aligned in structure, with grade-level and course-level domains used as the native reporting/coverage structure.

Blueprint & weighting

Missouri publishes grade-level and EOC blueprints, but the accessible official pages in this pass did not expose the domain-by-domain percentage tables. The assessment page states that item specifications organize expectations by domains/strands and that blueprints are available for grade-level and EOC assessments.

A cyclist rode 6363 kilometers in 1.51.5 hours at a constant speed. What was the cyclist's speed, in kilometers per hour?

Speed = 631.5=42\dfrac{63}{1.5} = 42 kilometers per hour.

Solve for yy: 64=y24\dfrac{6}{4} = \dfrac{y}{24}.

Cross-multiply: 4y=1444y = 144, so y=36y = 36.

What is the yy-intercept of the line y=12x−4y = \dfrac{1}{2}x - 4?

In y=mx+by = mx + b, the yy-intercept is b=−4b = -4.

Let p(x)=kx−6p(x) = kx - 6 for some constant kk. If p(2)=10p(2) = 10, what is the value of p(5)p(5)?

Substitute x=2x = 2: 2k−6=102k - 6 = 10, so 2k=162k = 16 and k=8k = 8. The rule is p(x)=8x−6p(x) = 8x - 6, so p(5)=8(5)−6=40−6=34p(5) = 8(5) - 6 = 40 - 6 = 34.

A gym charges a $30\text{\char36}30 monthly membership plus $5\text{\char36}5 for each fitness class. Let xx be the number of classes and yy be the total monthly cost in dollars. Which equation models the situation?

Each class adds $5\text{\char36}5 (slope) on top of the $30\text{\char36}30 membership (intercept), so y=5x+30.y = 5x + 30\textsf{.}

Practice playeasy

What is the slope of the line through (0,5)(0, 5) and (4,−3)(4, -3)?

Slope =−3−54−0=−84=−2.= \dfrac{-3 - 5}{4 - 0} = \dfrac{-8}{4} = -2\textsf{.}

Practice playeasy

A paint mixture uses red and blue paint in a ratio of 44 to 77. How many ounces of blue paint are needed to mix with 3232 ounces of red paint?

Scale the ratio: 3232 oz red is 88 groups of 44, so blue paint = 8×7=568 \times 7 = 56 ounces.

Practice playeasy

Solve for xx: 963=6x\dfrac{9}{63} = \dfrac{6}{x}.

Cross-multiply: 9x=63⋅6=3789 x = 63 \cdot 6 = 378. So x=42x = 42.
