Allie knows that a line passes through the point (-2,5) and has slope of -1/2, but she needs to find the equation of the line. She decides to use the point slope formula.

Which values should she replace with x1, y1, and m?

• x1: 5

  y1: -2

  m: -1/2

• x1: -5

  y1: 2

  m: -1/2

• x1: -2

  y1: 5

  m: -1/2

• None of these

Consider the linear equation in point-slope form. Name the slope and the point the line passes through.

y - 4 = -2(x + 3)

• Slope: -2

  Point: (-3, 4)

• Slope: -2

  Point: (3, 4)

• Slope: 2

  Point: (-4, 3)

• Slope: -2

  Point: (-4, 3)

What the slope intercept form of the line that passes through the two points: (3, -5) and (2, -1) ?

• y=-4x+17

• y=-4x+7

• y=6x-13

• y=6x-23

What is the slope of the line parallel to the line shown?

• 2/3

• 3/4

• -3/4

• 4/3

You and some friends are headed to the movies, and one of your friends is paying for everyone to go plus their "Gold Ticket" food and beverage packages! If all the tickets costs $62 and each food/beverage package is $10, which equation below shows the total amount it will cost?

• y=10x + 62

• y=62 + 10

• y=62x + 10

• y-10 = 62 + x
