Front

What is the definition of slope?

Back

The ratio of the change in y to the change in x (rise over run).

Front

What is the y-intercept in a linear equation?

Back

The value of y when x = 0.

Front

What is the difference between standard form and slope-intercept form?

Back

Standard form is Ax + By = C; slope-intercept form is y = mx + b.

Front

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

Back

Slope (m) = (y₂ - y₁) / (x₂ - x₁).

Front

What does the variable m represent in the equation y = mx + b?

Back

The slope of the line.
