Section 4.1 2A

Given that the slope is  2/3 and the y intercept is -3 what is the equation of the line?

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

Given that the slope is  -4 and the y intercept is -4 what is the equation of the line?

• y = 4x - 4
• y = -4x - 4
• y = -4
• y = -4x + 4

 Identify the slope and y intercept to write an equation of the line.

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

What does 'b" represent in
y = mx + b

• x-intercept
• nothing
• slope

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

• y-intercept
• slope
• macaroni
• nothing

Write the equation of the line.

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