Front

What is the definition of a linear function?

Back

A function that graphs to a straight line, defined by the equation y=mx+b.

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 between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the quadratic formula?

Back

x = (-b ± √(b²-4ac)) / (2a) for the equation ax² + bx + c = 0.

Front

What does it mean for a function to be quadratic?

Back

A function that can be expressed in the form f(x) = ax² + bx + c, where a ≠ 0.
