Answer:
![y = 0.5x + 5](https://tex.z-dn.net/?f=y%20%3D%200.5x%20%2B%205)
Step-by-step explanation:
As you can see the value of y increases uniformly with x, so this is a straight line. A straight line follows the formula of
![y = mx + c](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20c)
When x=0, y=5, and therefore c=5
![y = mx + 5](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%205)
Use the formula of slope to calculate slope
![m = \frac{5.5 - 5}{1 - 0} \\ m = 0.5](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B5.5%20-%205%7D%7B1%20-%200%7D%20%20%5C%5C%20m%20%3D%200.5)
Answer:
3 and 6
Step-by-step explanation:
GCF's or greatest common factors of numbers 1 to 8
1 : 1
2 : 1, 2
3: 1 , 3
4 : 1, 2, 4
5 : 1, 5
6 : 1, 2, 3, 6
7 : 1, 7
8 : 1, 2, 4, 8
3 and 6 have 3 as their GCF
<u>Part 1: Finding radius</u>
The radius of a circle is defined as the distance from the center to a point on the circle's circumference.
Using the distance formula,
![r=\sqrt{(-7-8)^{2}+(-1-7)^{2}}=\boxed{17}](https://tex.z-dn.net/?f=r%3D%5Csqrt%7B%28-7-8%29%5E%7B2%7D%2B%28-1-7%29%5E%7B2%7D%7D%3D%5Cboxed%7B17%7D)
<u>Part 2: Finding the point with x-coordinate -15</u>
Let the y coordinate of the point be y. Then, we have the point (-15, y). Substituting into the distance formula,
![\sqrt{(-15-(-7))^{2}+(-1-y)^{2}}=17\\\\64+(-1-y)^{2}=289\\\\(-1-y)^{2}=225\\\\-1-y =\om 15\\\\y=\boxed{-16, 14}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-15-%28-7%29%29%5E%7B2%7D%2B%28-1-y%29%5E%7B2%7D%7D%3D17%5C%5C%5C%5C64%2B%28-1-y%29%5E%7B2%7D%3D289%5C%5C%5C%5C%28-1-y%29%5E%7B2%7D%3D225%5C%5C%5C%5C-1-y%20%3D%5Com%2015%5C%5C%5C%5Cy%3D%5Cboxed%7B-16%2C%2014%7D)
