Parallel and Perpendicular Equations

Front

What is the slope of a line that is perpendicular to a line with slope m?

Back

The slope of a line that is perpendicular to a line with slope m is -1/m.

Front

Write the equation of a line in slope-intercept form.

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

Back

The slope of the line is 3.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).
