If two lines have the same slope, they are parallel.
If the product of 2 slopes is -1, the lines are perpendicular.
10. The lines do not have the same slope, so they are not parallel.
3 * (-1) = -3. The product is not -1, so the lines are not perpendicular.
Answer: neither
11. 2/3 and -3/2 are not equal, so the lines are not parallel.
2/3 * (-3/2) = -6/6 = -1
The product of the slopes is -1, so the lines are perpendicular.
Answer: perpendicular
12.
Plot the points (2, 16) and (5, 40).
Draw a line though them.
Then you can use the slope formula to find the slope.
m = (y2 - y1)/(x2 - x1) = (40 - 16)/(5 - 2) = 24/3 = 8
Answer:
Step-by-step Solution:
<u>Simplify by subtracting 18 both sides</u>
- 7x + 18 > -3
- => 7x + 18 - 18 > -3 - 18
- => 7x > -21
- => x > -3
Hence, the solution to the inequality is x > -3.
Answer:
(1,5)
Step-by-step explanation:
The x coordinate of the midpoint is found by adding the x coordinates and dividing by 2
(6+-4)/2 = 2/2 =1
The y coordinate of the midpoint is found by adding the x coordinates and dividing by 2
( (8+2)/2 = 10/2 = 5
The mid point is (1,5)
