Front

What is the definition of a linear equation?

Back

An equation that makes a straight line when graphed.

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 does it mean for two lines to be parallel?

Back

They have the same slope and will never intersect.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.
