- 1. Multiple Choice
Which equation goes through the points:
(6, 9) and (3, 5)
y = -4/3x + 18
y = -4/3x + 17
y = 4/3x + 1
y = 4/3x - 6
- 2. Multiple Choice
Admission to the local amusement park costs $5.25, and each ride ticket costs $2.50. Which of the following equations represents the cost C, in dollars, for admission to the park with x ride tickets?
C = 2.50 + 5.25x
C = 5.25 + 2.50x
C = 7.75 + x
C = 7.75x
- 3. Multiple Choice
Which of the following linear equations is a line that passes through the point (- 2, - 4) and is parallel to the given line?
y = x - 2
y = -2x - 8
y = 1/2x - 3
y = - 2x - 3
- 4. Multiple Choice
Which equation represents the line that is parallel to 5x + y = 13 and passes through the point (15, - 31)?
y = -5x + 44
y = -5x - 140
y = 5x - 106
y = 5x + 170
- 5. Multiple Choice
Which equation is perpendicular to
y = 4x – 6 and passes through point
(8 , 12)?
y = 4x – 20
y = – 1/4 x + 14
y = 4x + 44
y = 1/4 x + 10
- 6. Multiple Choice
Which equation represents a line that is perpendicular to y = 2/3 x – 5 and passes through the point (6, 12)?
y = 2/3 x – 2
y = 2/3 x + 8
y = – 3/2 x + 24
y = – 3/2x + 21
- 7. Multiple Choice
Which equation represents a line that is parallel to the x–axis?
x = 3
y = 4
x = y
y = x + 1
- 8. Multiple Choice
Line G is parallel to the y–axis. It also passes through the x–axis at the point
(–6, 0). What is the equation and the slope of line G?
x = - 6
slope = 0
y = - 6
slope = 0
x = - 6
slope = undefined
y = - 6
slope = undefined
- 9. Multiple Choice

- 10. Multiple Choice
A person is waiting in line to get into a sporting event. The data in the table represents the relative position, in feet, of the person to the entry gate over time in seconds.
What does the slope of the linear equation that models the data represent?
The person’s speed is increasing as the person approaches the entry gate.
The person’s speed is decreasing as the person approaches the entry gate.
The person is moving closer to the entry gate at a rate of 1.5 feet per second
The person is moving farther away from the entry gate at a rate of 1.5 feet per second
- 11. Multiple Choice
Which line has a y–intercept of 2?
Line A
Line B
Both of them
Neither one
- 12. Multiple Choice
What are the x– and y–intercepts of the line 3x – 5y = 2?
x–intercept = 2/3 , y–intercept = – 2/5
x–intercept = – 2/3 , y–intercept = 2/5
x–intercept = 2/5 , y–intercept = – 2/3
x–intercept = – 2 5 , y–intercept = 2 3
