Lesson 21: Point-Slope FormMAFS.912.A.3.8 Graph a line given any of the following
information: a table of values, the x- and y-intercepts, two points, the slope and a point, the equation of the line in slope-intercept
form, standard form, or point-slope form .
Bellwork:
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:
