MULTIPLE CHOICE QUESTION
30 sec • 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
30 sec • 1 pt
how one quantity changes in relation to another quantity
rate of change
equivalent ratios
constant
proportional
linear
Answer explanation
The rate of change is how one quantity changes in relation another ( Δy/Δx ).
Although a proportional relationship and a linear relationship are two ways that quantities may change in relation to each other, there are other ways. Equivalent ratios and are static (not changing). Constant means "not changing".

MULTIPLE CHOICE QUESTION
30 sec • 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
30 sec • 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.

MULTIPLE CHOICE QUESTION
30 sec • 1 pt
equal to the rate of change ( Δy/Δx )
linear
equivalent ratios
intercepts
slope
proportional
Answer explanation
The slope is equal to the rate of change ( Δy/Δx ).
If the slope is constant, the relationship will be linear. If the slope is constant and the graph intersects the origin, it is a proportional relationship. x- and y-intercepts occur for straight lines as well as other relationships.

MULTIPLE CHOICE QUESTION
30 sec • 1 pt
ratios that simplify to the same value
linear
equivalent ratios
intercepts
slope
constant
Answer explanation
Equivalent ratios are ratios that simplify to the same value.
The slope is equal to the rate of change ( Δy/Δx ). Linear relationships produce a straight line when graphed.
x- and y-intercepts are where the graph crosses the x- and y-axes. Constant means "not changing".
