Find the slope and y-intercept. 5x - 3y = 6 Write it in slope-intercept form. (y = mx + b) 5x – 3y = 6 -3y = -5x + 6 y = x - 2 m = b = -2 (0,-2) -3 -3 -3

Find the slope and y-intercept. 2y + 2 = 4x Write it in slope-intercept form. (y = mx + b) 2y + 2 = 4x 2y = 4x - 2 y = 2x - 1 2 2 m = 2 2 1 b = -1 (0,-1) 2

Find the slope and y-intercept of y = -2x + 4 m = 4; b = -2 m = 4; b = 2 m = -2; b = 4 m = − 2 1 ; b = (0,4)

Find the slope and y-intercept of y = -x - 3 m = 0; b = 3 m = -1; b = 3 m = -1; b = -3 m = 0; b = -3

y = -3x – 4 y = -4x – 3 y = -3x + 4 y = -4x + 3 Write the equation of a line that has a y-intercept of -3 and a slope of -4. y = -3x – 4 y = -4x – 3 y = -3x + 4 y = -4x + 3

y = 𝟏 −𝟐 x + 3 y = 𝟏 −𝟐 x – 3 y =- 𝟏 𝟐 x – 3 y = −𝟏 𝟐 x + 3 Write the equation of a line that has a slope of −𝟏 𝟐 and a y-intercept of -3 y = 𝟏 −𝟐 x + 3 y = 𝟏 −𝟐 x – 3 y =- 𝟏 𝟐 x – 3 y = −𝟏 𝟐 x + 3

y – 11 = 4(x -1) y + 5 = 4(x + 3) y = -3x + 1 y= 4x +7 Write an equation of the line that goes through the points (-3, -5) and (1, 11). y – 11 = 4(x -1) y + 5 = 4(x + 3) y = -3x + 1 y= 4x +7
