Objective The student will be able to: Write the equation of a line given the slope and y-intercept. Identify slope and y-intercept from an equation.

b represents the y-intercept Important!!! Slope – Intercept Form y = mx + b m represents the slope b represents the y-intercept

To write the equation of a line in slope-intercept form (y = mx + b) given the slope and y-intercept . Write the equation of the line given: m = -3, b = 2 Plug in the slope and y-intercept. y = mx + b m = -3, b = 2 so y = -3x +2

Find the slope and y-intercept. y = 3x – 7 y = mx + b m = 3, b = -7 To find the slope and y-intercept of an equation, write the equation in slope-intercept form: y = mx + b. Find the slope and y-intercept. y = 3x – 7 y = mx + b m = 3, b = -7

Find the slope and y-intercept. y = x y = mx + b y = x + 0 3) y = 5 y = 0x + 5 m = b = 0 m = 0 b = 5

Find the slope and y-intercept. 4) 5x - 3y = 6 Write it in slope-intercept form. (y = mx + b) 5x – 3y = 6 -3y = -5x + 6 y = x - 2 -3 -3 -3 m = b = -2

Find the slope and y-intercept. 5) 2y + 2 = 4x Write it in slope-intercept form. (y = mx + b) 2y + 2 = 4x 2y = 4x - 2 y = 2x - 1 2 2 2 m = 2 b = -1

Find the slope and y-intercept of y = -2x + 4 m = 2; b = 4 m = 4; b = 2 m = -2; b = 4 m = 4; b = -2
