What type of slope?

• zero slope
• undefined
• negative
• positive

What does "m" stand for in the slope formula?

• y axis

• slope

• y coordinate

• x coordinate

3x + y = 12

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

What is the first step in solving for y?

-2x + 4y = 12

• add 2x

• subtract 4y

• divide by -2

• subtract 12

What is the first step in solving for y?

5x - y = 16

• add y

• divide by 5

• subtract 5x

• add 5x

Put the equation in Slope-Intercept for by solving for y.

10x - 2y = 6

• y = 5x - 3
• y = -5x + 3
• -2y = -10x + 6
• y = 1/5x - 1/3

What is the y-intercept of the line?

b = ?

• b = -1

• b = 4

• b = 2

• b = 3

What is the slope in the picture?

• Positive
• Negative
• Zero
• Undefined
