• {-4, -1, 0, 2, 7}
• {-5, -4, -1, 0, 1, 2, 4, 7}
• {-5, 0, 1, 2,. 4}
• {5}

What is the equation of the line that has a slope of 0 (zero) and passes through the point (6, -8)?
Hint:  Is it horizontal or vertical?

• x = 6
• y = 6
• x = -8
• y = -8

Hint:  Put each answer choice into slope-intercept form, solving for y.  Then put the equations in the calculator and observe the graphs.

• -3x + 3y + 16 =n 0
• 3x - 8y + 16 = 0
• -3x - 8y - 16 = 0
• 3x + 8y - 16 = 0

Hint:  Graph each of the answer choices.  Then just compare.

• II and IV
• I and III
• II and III
• I and IV

Hint:  Parallel lines have the same slope.

• y = 2x - 1
• y = ½x - 1
• y = -½x - 1
• y = -2x - 1
