Question

Match the vocabulary terms to the correct definitions. 1. a speed or rate of change where the denominator (or second quantity measured) in the ratio is 1 direct variation 2. describes variation between proportional relationships slope 3. the ratio of vertical change to horizontal change rate of change 4. a ratio describing vertical change to horizontal change of a linear relationship on a coordinate grid unit rate 5. a number, k, that represents the unit rate used in a direct variation equation y = kx for comparing proportional relationships between two variables x and y found by using division constant of proportionality

Answer 1

The vocabulary terms have been matched to the correct definitions as follows;

• Direct variation: describes variation between proportional relationships

• Slope: a ratio describing vertical change to horizontal change of a linear relationship on a coordinate grid

• Rate of change:  a number, k, that represents the unit rate used in a direct variation equation y = kx for comparing proportional relationships between two variables x and y found by using division

• Unit rate: a speed or rate of change where the denominator (or second quantity measured) in the ratio is 1

• Constant of proportionality: the ratio of vertical change to horizontal change rate of change

What are Mathematical Terms?

• Mathematical terms refer to phrases and words that define certain arithmetic standards.

• The above are the definitions of the mathematical terms. Direct variation, for instance, expresses the relationship between two variables, x, and y.

• The slope is often used after graphing and indicates the relationship of change between the vertical and horizontal axes.
