XY55.2 Point-Slope FormTodays Schedule:Lesson 5.2 PowerpointIn class assignment/homeworkExit SlipGOAL: Use point-slope form to write the equation of a line.KEY WORDS: slope, point-slope form
5.2 Point-Slope FormPOINT-SLOPE FORM OF THE EQUATION OF A LINE
The point-slope form of the equation of the line through (x1, y2) with slope m is
y y1 = m(x x1)
WRITING EQUATIONS Write in point-slope form the equation of the line that passes through the given point and has the given slope.

(3, 4)WRITING EQUATIONS OF PARALLEL LINES Write in slope-intercept form the equation of the line that is parallel to the given line and passes through the given point.
y = 7x 1
(8, 0)CHOOSING A FORM Now you know two ways to write linear equations: slope-intercept form or in point-slope form. Depending on the information you are given, sometimes it is easier to write a linear equation in one form rather than the other.
