Solving for y & Identify Slope & Intercept
Day 12 Objective: 3.03, 4.01
Examples1) 2x + 5y = 8 2) 2x = 8 + y
Examples3) -3x + 2y = 4 4) 5x – y = 8
Examples5) 6)

1 32 xy
Vocabulary
Slope-Intercept Form: y = mx + b
m – slope b – y-intercept
Examples
Find the slope and y-intercept of each equation.
7) y = -2x + 1 10) y = ½ x – 5
8) y = ⅝x 11) y = 5
9) 2x + 3y = 7 12) -3x – 2y = 14
Examples
Write an equation in slope-intercept form.
13) m = 3, b = 4 15) m = -2, b = 8
14) m = 0, b = -3 16) m = undefined, b = 4
Examples
Write the equation of the line.17) 18)
