Answer:
Step-by-step explanation:
Insert the given x values for the given equation to find the corresponding y coordinate:
Insert -6:
Simplify multiplication (when multiplying a negative and a positive, the result will always be negative):
Simplify (when subtracting from a negative number, add the values, but keep the negative symbol):
Insert -1:
Insert 1:

Answer:
14. D
15. A
16. A
Step-by-step explanation:
14. Point slope form formula: y-y₁=m(x-x₁).
When graphing you always want to think x/y for your slope.
X-axis increases by 2 and the Y-axis increases by 10, which would make the slope (m) 2/10 = 1/5.
If your slope is does not come out correct, then you can prove your point.
15. The given information is (-2,2): m=-1.
Given the Point slope formula: y-y₁=m(x-x₁), you can replace m to -1, y₁=2 and x=+2. (Two negatives would make a positive.)
Your answer: y-2=-(x+2)
16. Given: y=4x-7; (3,0)
Parallels lines: Same slope different y-intercepts.
A and D has the same slope and different y-interecepts, but your answer would be A because the equation that was given as a negative y-intercepts.
Answer:
10a + 6
Step-by-step explanation:
3a + 4 + 2a - 1
5a + 3
2( 5a + 3)
10a + 6
About 115°
Step-by-step explanation:
- By 2 pi r, total circumference is about 942
- Length of an arc = 2 pi r (theta/360)
- We needed to find theta(angle) here
- Easily putting all the values gives us 115°
