Writing Equations in Point-Slope Form parallel and perpendicular

Front

What is the point-slope form of a linear equation?

Back

The point-slope form is given by the equation y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Front

How do you determine if two lines are parallel?

Back
