Look at the formula to find it example 1 Use a little algebra to get the equation in the right form example 2. For this one they give you a point x1 y1 and a slope m and have you plug it into this formula. Have a play with it first move the point try different slopes.
Slope y 2 y 1 x 2 x 1 How it works.
Finding the Slope of a Linear Equation. Check the equation for varying terms and constant terms. Slope y 2 y 1 x 2 x 1 text Slope. An equation in the slope-intercept form is written as y m x b Where m is the slope of the line and b is the y-intercept.
