Front

What is the equation and slope of the line y = 3?

Back

y = 3; slope is zero

Front

Define a direct variation. Give an example.

Back

A direct variation is a relationship where one variable is a constant multiple of another. Example: y = kx.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as x increases, f(x) also increases.

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output for each input.
