1 MA 15200 Lesson 23 Parts of Sections 2.3 and 2.4 I Review of Equations of Lines In the last lesson we found two forms for equations of lines Point-Slope Form: 11 () y y m x x Slope-Intercept Form: y mx b  Any non-vertical line can be written in both of the forms. Point-Slope Form An equation of a form y y m x x is an equation for a line in point-slope form. The value of m is the slope of the line and the ordered pair, ( , ) xy , is an indicated point of the line. Slope-Intercept Form An equation of the form y mx b is an equation for a line in slope-intercept form. The value of m is the slope of the line and b or point (0, b ) is the y -intercept of the line. Ex 1: Write an equation in point-slope form for the line shown. Convert to slope- intercept form. 2 2 x y
