Front

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

Back

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

Front

What does the equation y = mx + b represent?

Back

It represents the slope-intercept form of a linear equation, where m is the slope and b is the y-intercept.

Front

If the slope of a line is positive, what does that indicate about the line's direction?

Back

The line rises from left to right.

Front

What is the y-intercept in the equation y = 2x + 3?

Back

3

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

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