Match the graph with its equation:

What is the y-intercept shown on the graph?

• (0, -2)

• (3, 0)

• (0, 3)

• None of these.

Multiply:
(3x – 1)(x + 5) 

• 3x² + 4x + 5

• 3x² + 4x - 5

• 3x² + 14x + 5

• 3x² + 14x - 5

Simplify:
(x - 7)(x + 7)

• x² + 7x - 49

• x² - 7x + 49

• x² - 49

• x² + 49

Simplify
(p − 8)²

 Hint: (p − 8)² = (p − 8)(p − 8)

• p ² − 16p − 64 

• p ² + 16p + 64 

• p ² − 16p − 8

• p ² − 16p + 64 

Find the product:
(x + 12)(x - 12)

• x² - 144

• x² + 144

• x² + 12x - 144

• x² - 12x + 144

What does "m" represent in y=mx+b?

• y-intercept

• slope

• macaroni

• nothing

Which of these represents slope-intercept form?

• y - y₁ = m(x-x₁)

• Ax + By = C

• y = mx + b

What type of slope does the following graph have?

• Postive

• Negative

• Zero Slope

• Undefined

Which value represents the slope in the following equation:

y= 1/2x + 8

• 8

• 1

• 2

• 1/2
