Rewrite the equation in slope intercept form (Solve for y):
 -5x + 6y = 12

• 6y = 5x + 12
• y = (5/6)x + 2
• y = (-5/6)x + 2
• y = (-5/6)x + 12

Determine the slope and y-intercept from the following equation:   4x + y = -10

• slope: 4   y-intercept:  (0,10)
• slope: -4   y-intercept:  (0,-10)
• slope: -4   y-intercept:  (0,10)
• slope: 4   y-intercept:  (0,-10)

5x + y = -10

• y = 5x + 10
• y = -5x - 10

3x + y = 12

• y = -3x +12
• x = y + 4
• x = y + 12
• y = 3x -12

Solve for y:
2x + 2y = 6

• y = - x + 3
• y = x + 3
• y = 2x +6
• y = - 2x + 6
