MULTIPLE CHOICE QUESTION

1 min • 1 pt

a relationship that produces a straight line when graphed

rate of change

equivalent ratios

axis

slope

linear

Answer explanation

A linear relationship produces a straight line when graphed. The rate of change is how one quantity changes in relation another. If the rate of change is constant, a straight line will be produced when graphed, but the rate of change of some relationships are not constant, so will not produce a straight line. The slope is equal to the rate of change, so will only produce a straight line when it is constant. An axis is a number line in a coordinate system.

MULTIPLE CHOICE QUESTION

1 min • 1 pt

quantities that have a constant ratio

rate of change

equivalent ratios

intercepts

proportional

slope

Answer explanation

Quantities are proportional if they have a constant ratio. The constant of proportionality is found by the ratio: y/x.

The rate of change is how one quantity changes in relation another. The slope is equal to the rate of change. x- and y-intercepts occur for straight lines as well as other relationships. Equivalent ratios are ratios that simplify to the same value.

MULTIPLE CHOICE QUESTION

1 min • 1 pt

a linear relationship that intersects the origin

rate of change

equivalent ratios

intercepts

slope

proportional

Answer explanation

Quantities are proportional if they have a constant ratio. When we graph a proportional relationship produces a straight line that intersects the origin.

The rate of change is how one quantity changes in relation another, and that relationship may or may not be proportional. If the rate of change is constant, a straight line will be produced when graphed, but the line will only intersect the origin if the relationship is also proportional. The slope is equal to the rate of change. x- and y-intercepts occur for straight lines as well as other relationships.
