1 Warm Up Write an equation given the slope and y-intercept Write an equation of the line shown.

2 EXAMPLE 1 Write an equation given the slope and y-intercept From the graph, you can see that the slope is m = 4 and the y-intercept is b = 2. Use slope-intercept form to write an equation of the line. y = mx + b y = x + ( 2) 4 y = x ( 2) 4 Use slope-intercept form. Substitute for m and 2 for b. 4 Simplify.

3 GUIDED PRACTICE for Example 1 Write an equation of the line that has the given slope and y - intercept. 1. m =, b = 1 Use slope intercept point form to write an equation of the line y = mx + b Use slope - intercept form. y = x + 1 Substitute for m and 1 for b. y = x + 1 Simplify.

6 EXAMPLE 2 Write an equation given the slope and a point Write an equation of the line that passes through (5, 4) and has a slope of. Because you know the slope and a point on the line, use pointslope form to write an equation of the line. Let (x 1, y 1 ) = (5, 4) and m =. y y 1 = m(x x 1 ) Use point-slope form. y 4 = (x 5) Substitute for m, x 1, and y 1. y 4 = x + 15 y = x + 19 Distributive property Write in slope-intercept form.

7 EXAMPLE Write equations of parallel or perpendicular lines Write an equation of the line that passes through ( 2,) and is (a) parallel to, and (b) perpendicular to, the line y = 4x + 1. a. The given line has a slope of m 1 = 4. So, a line parallel to it has a slope of m 2 = m 1 = 4. You know the slope and a point on the line, so use the point-slope form with (x 1, y 1 ) = ( 2, ) to write an equation of the line.

8 EXAMPLE Write equations of parallel or perpendicular lines y y 1 = m 2 (x x1) y = 4(x ( 2)) y = 4(x + 2) y = 4x 8 y = 4x 5 Use point-slope form. Substitute for m 2, x 1, and y 1. Simplify. Distributive property Write in slope-intercept form.

The given line has a slope of m 1 =. So, a line parallel to it has a slope of m 2 = m 1 =. You know the slope and a point on the line, so use the point - slope form with (x 1, y 1 ) = (4, 2) to write an equation of the line. y y 1 = m 2 (x x 1 ) Use point-slope form. y ( 2) = (x 4) Substitute for m 2, x 1, and y 1. y + 2 = (x 4) Simplify. y + 2 = x 12 Distributive property y = x 14 Write in slope-intercept form.

12 GUIDED PRACTICE for Examples 2 and b. A line perpendicular to a line with slope m 1 = has a slope of m 1 2 = 1 = m 1 Use point - slope form with (x 1, y 1 ) = (4, 2) y y 1 = m 2 (x x 1 ) 1 y ( 2) = (x 4) 1 y + 2 = (x 4) 1 4 y + 2 = x 1 2 y = x Use point-slope form.
