The line through (3,6) and (3,15) is vertical so the perpendicular slope is a horizontal line.
y=7
Answer: Choice number three is the correct choice: slope = –2, y-int = 4
Explanation: Slope-intercept form, y=mx+b, of linear equations, emphasizes the slope and the y-intercept of the line. In this case, number 4 is considered b in this equation which makes it the y-intercept. Remember that the number with the x in an equation such as this is the slope.

Answer:
Michael needs to purchase 1 5/8 feet more of metal flashing.
Step-by-step explanation:
To have the same denominator in both fractions, you can multiply 4 by 2. This will turn out to be 8, resulting in 8 being our common denominator. To achieve this, multiply:
<u>7</u> x <u>2</u> = <u>14</u> or 1 6/8
4 2 8
We next add both fractions together, resulting in:
3 1/8 + 1 6/8 = 4 7/8
The fraction 6 1/2 can also be expressed as 6 4/8, so to find out how much metal Michael still needs to purchase, subtract 4 7/8 from 6 4/8.
Answer:
There is 2145.52 cubic inches of air in the ball
Step-by-step explanation:
A round ball is an example is hollow sphere. In order to find how much air the ball holds, the volume of the sphere needs to be found.
Given
Radius = r = 8 in
The volume of sphere is given by:
![V = \frac{4}{3} \pi r^3](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E3)
Putting the values we get
![V = \frac{4}{3} * \frac{22}{7} * (8)^3\\V = \frac{4}{3} * \frac{22}{7} * 512\\V = \frac{45056}{21}\\V = 2145.52\ in^3](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%20%5Cfrac%7B22%7D%7B7%7D%20%2A%20%288%29%5E3%5C%5CV%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%20%5Cfrac%7B22%7D%7B7%7D%20%2A%20512%5C%5CV%20%3D%20%5Cfrac%7B45056%7D%7B21%7D%5C%5CV%20%3D%202145.52%5C%20in%5E3)
Hence,
There is 2145.52 cubic inches of air in the ball
