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 is a function in mathematical terms?

Back

A function is a relation where each input (x) has exactly one output (y).

Front

What is the difference between independent and dependent variables?

Back

Independent variables are manipulated (x), while dependent variables are measured (y).
