Changing from point slope form to slope-intercept form:• Clear the fraction, if any, by multiplying everything except the inside of the

parentheses by the denominator.• Distribute• Move the X term to the right side by doing the opposite of it.• Divide every term by the number attached to y.• Examples:

Writing an equation from two points:• Find the slope using the slope formula: m= • Choose one of the two points• Using the slope you calculated and the point you chose, plug into point-slope form: = m

(x - )• Change the equation to slope-intercept form• Example:
