Answer:
9. Perpendicular
10. neither
11. Perpendicular
12. neither
Step-by-step explanation:
------------------
Slope Intercept Form: y = mx + b
* M is the slope
* B is the y intercept
------------------
Lines are parallel if they have the same slope (ex. If two equations have a slope of 2)
Lines are perpendicular if they have the opposite and the reciprocal slope (ex. If 1 equation has a slope of 3 and another equation has a slope of - )
------------------
9. Perpendicular: The slopes are reciprocal of each other and one of them is negative
10. Neither: The lines are not perpendicular because the slopes are both negative
11. Perpendicular: If you plot y=5 it is a horizontal line through 5. If you plot x=-3 it is vertical line through -3. These lines intercept and are perpendicular.
12. Neither: The slopes of both equations need to be the same to be parallel
- Put both equations into y=mx+b
- y = 1/2x -2 AND y = -1/2x -2
Answer:
U, D, L
Step-by-step explanation:
E: 22 × 1.3 = 28.6, Up.
F: 7.25 × 6.5 = 47.13 (Rounded), Down.
G: 212 × 0.99 = 209.88, Left.
Up, Down, Left = U, D, L
