Answer:
Step-by-step explanation:
System 1 has no solution, and System 2 has infinitely many solutions. Wait, YOUR IN HIGH SCHOOL?! IM IN 8TH GRADE AND IM DOING THIS??!! well, idk how to solve this, but these are the answers.
<u>Hello:</u>
<u />
<u>Okay, this problem should be taken in a series of steps</u>:
<u>What is the slope's formula?</u>
![\rm\hookrightarrow \frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Crm%5Chookrightarrow%20%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
- (x₁,y₁) -- first point
- (x₂,y₂) -- second point
<u>Okay, now let's use this knowledge</u>
10. (5,-19) and (-5,21)
![Slope = \frac{21--19}{-5-5} =\frac{40}{-10}=-4](https://tex.z-dn.net/?f=Slope%20%3D%20%5Cfrac%7B21--19%7D%7B-5-5%7D%20%3D%5Cfrac%7B40%7D%7B-10%7D%3D-4)
11. (12,1) and (12, -1)
![Slope = \frac{-1-1}{12-12} =\frac{-2}{0}](https://tex.z-dn.net/?f=Slope%20%3D%20%5Cfrac%7B-1-1%7D%7B12-12%7D%20%3D%5Cfrac%7B-2%7D%7B0%7D)
12. (8,7) and (4,7)
![Slope = \frac{7-7}{4-7} =0](https://tex.z-dn.net/?f=Slope%20%3D%20%5Cfrac%7B7-7%7D%7B4-7%7D%20%3D0)
<u>Answer:</u>
- Question 10: -4
- Question 11: undefined
- Question 12: 0
Hopefully that helps!
Hey
Answer: 4
How do you find that out?
Divide the two numbers on the right, 36 and 8.
36/8=4
7 * 4 + 8 = 36
Hope this helped
