Middle School Math Vocabulary Part 7

constant of proportionality

• the unit rate in a proportional relationship

• the starting output of a function

• the ratio of vertical change (change in y) to horizontal change (change in x) in a function; the rate at which the quantity represented by y increases or decreases with respect to a change in the quantity represented by x.

• a function with a graph that is a non-vertical straight line; which can be represented by a linear equation in the form y = mx + b

initial value
