Slope-Intercept Form
Writing the Equation
Example
Write the equation of the line containing the points (3, 2) and (-2, 4) in slope-intercept form.
Step 1. Findthe slope of the line, m using the slope formula.
Step 2. Substitute the values for one point (3, 2) and the value for m of 
into the slope-intercept form and solve for b.
Step 3. Substitute m and b into the slope-intercept form.
Step 4. Check the solution by substituting values of the second point into the equation.
