Slope & Graphing Linear Equations Review

Front

What is the slope formula?

Back

The slope formula is given by \( m = \frac{y_2 - y_1}{x_2 - x_1} \), where \( m \) is the slope, and \( (x_1, y_1) \) and \( (x_2, y_2) \) are two points on the line.

Front

How do you find the slope of a line given two points?

Back

To find the slope, use the formula \( m = \frac{y_2 - y_1}{x_2 - x_1} \). Substitute the coordinates of the two points into the formula.

Front

What is the slope of the line containing the points (2, 3) and (2, 7)?

Back

The slope is undefined because the x-coordinates are the same.

Front

What is the slope of the line containing the points (1, 2) and (4, 5)?

Back

The slope is \( \frac{5 - 2}{4 - 1} = \frac{3}{3} = 1 \).
