Find the slope-intercept equation

• y = 4x + 6

• y = -4x - 6

• y = 1/4x - 6

• y = -1/4x + 6

From the equation: y = -2x +6 what is the slope of the line?

• y

• 6

• x

• -2

Solve this equation in standard form so that it is in slope intercept form 4x-2y = 20

Find the equation of the line in slope-intercept form. 

• y = - 1/4x - 3
• y = 1/3x + 3
• y = - 1/4x + 2
• y = 1/3x -3

Find the slope and y-intercept of the following:

3x - y = 9

• Slope = 3, y-intercept = -9
• Slope = 9, y-intercept = 3
• Slope = 3, y-intercept = 9
• Slope = -1, y-intercept = 3

Find the slope  and y-intercept of:

2x - 3y = -12
