Identify the slope and the y- intercept of the equation

y = 23 - 1/2x

• y-int = 1/2 , slope = 23

• y-int = 1/2, slope = 23

• y-int = 23, slope = -1/2

• y-int = 23, slope = 1/2

Write the equation in slope intercept form (y = mx + b)

12x - 4y = 24

• y = 3x + 6

• y = 3x - 6

• y = 6x + 3

• y = -6x -3
