Front

A linear relationship between two variables, x and y, that can be written in the form y = kx, where k is a nonzero constant.

Back

Direct variation

Front

The constant k in direct and inverse variation equations. Example: In y = 5x, the constant of variation is 5.

Back

Constant of variation

Front

The slope-intercept form of a linear equation is $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept. Example: $y = -2x + 4$. The slope is -2. The y-intercept is 4.

Front

The point-slope form of a linear equation is $y - y_1 = m(x - x_1)$, where $m$ is the slope and $(x_1, y_1)$ is a point on the line. Example: $y - 3 = 2(x - 3)$.

point-slope form

Front

A set of functions whose graphs have basic characteristics in common. Functions in the same family are transformations of their parent function.

Back
