What the test measures

Proportional Relationships and Lines skills

  1. Use slope and the equation of a line to solve problems.

  2. Graph proportional relationships and compare them when represented in different ways.

  3. Standards: 8.EE.5, 8.EE.6

Standards basis

Montana PK-12 Mathematics Content Standards / Common Core State Standards for Mathematics (CCSS-M)-aligned Montana standards — Montana

How the MAST reports it

Montana’s MAST is a state-specific through-year assessment built by New Meridian and aligned to Montana’s academic content standards, not a Smarter Balanced-style claims/targets framework. The math blueprints organize content into grade-level strands/testlets that map directly to CCSS-M-derived Montana standards.

Blueprint & weighting

The blueprint publishes a through-year design of 12 strands/testlets per grade, with 1 strand per testlet, 2 reporting attributes per strand, and 9–13 items per testlet. It also specifies approximate item-type and DOK distributions, but does not publish percentage weighting by domain in the captured blueprint text.

What is the yy-intercept of the graph of y=12x5y = 12x - 5 in the coordinate plane?

In y=mx+by = mx + b, the yy-intercept is the point (0,b)(0, b). Here b=5b = -5, so the yy-intercept is (0,5).(0, -5)\textsf{.}

What is the yy-intercept of the graph of y=9x14y = -9x - 14 in the coordinate plane?

In y=mx+by = mx + b, the yy-intercept is the point (0,b)(0, b). Here b=14b = -14, so the yy-intercept is (0,14).(0, -14)\textsf{.}

What is the yy-intercept of the graph of y=5x+27y = 5x + 27 in the coordinate plane?

In y=mx+by = mx + b, the yy-intercept is the point (0,b)(0, b). Here b=27b = 27, so the yy-intercept is (0,27).(0, 27)\textsf{.}

What is the yy-intercept of the graph of y=11x+6y = -11x + 6 in the coordinate plane?

In y=mx+by = mx + b, the yy-intercept is the point (0,b)(0, b). Here b=6b = 6, so the yy-intercept is (0,6).(0, 6)\textsf{.}

What is the yy-intercept of the graph of y=2x19y = 2x - 19 in the coordinate plane?

In y=mx+by = mx + b, the yy-intercept is the point (0,b)(0, b). Here b=19b = -19, so the yy-intercept is (0,19).(0, -19)\textsf{.}

Practice playeasy

What is the yy-intercept of the graph of y=8x3y = -8x - 3 in the coordinate plane?

In y=mx+by = mx + b, the yy-intercept is the point (0,b)(0, b). Here b=3b = -3, so the yy-intercept is (0,3).(0, -3)\textsf{.}

Practice playeasy

What is the yy-intercept of the graph of y=15x+4y = 15x + 4 in the coordinate plane?

In y=mx+by = mx + b, the yy-intercept is the point (0,b)(0, b). Here b=4b = 4, so the yy-intercept is (0,4).(0, 4)\textsf{.}

Practice playeasy

What is the yy-intercept of the graph of y=3x+22y = -3x + 22 in the coordinate plane?

In y=mx+by = mx + b, the yy-intercept is the point (0,b)(0, b). Here b=22b = 22, so the yy-intercept is (0,22).(0, 22)\textsf{.}
