• 4x
• 4
• x

What is the y-intercept in the following equation:  y=-4x-5

• -4
• -4x
• 5
• -5

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

• y-intercept
• slope
• macaroni
• nothing

If m=3 and b=6, what is the correct slope intercept equation?

• y=3-6
• y=3x-6
• y=3x+6
• y=6x+3

Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

• y + 7 = -1/4(x - 4)
• y - 4 = -1/4(x + 7)
• y + 7 = 4(x - 4)
• y - 7 = -1/4(x - 4)
