Front

Define the term 'slope' in the context of a linear equation.

Back

The slope is the measure of the steepness of a line, calculated as the rise over run.

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does it mean if a linear equation has no solutions?

Back

It means the lines represented by the equations are parallel and never intersect.

Front

What is the power of a power property in exponents?

Back

(a^m)^n = a^(m*n) where a is a base, m and n are exponents.
