Answer:
Step 1:
To find ordered pair solutions, you could create an x and y graph and fill out the x side. Then, plug in an x number to get your y number and graph the ordered pairs to see if they give you a straight line. I'm going to use these numbers: -1, 0, 1, and 2.

![\left[\begin{array}{ccc}-1&?\\0&?\\1&?\\2&?\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-1%26%3F%5C%5C0%26%3F%5C%5C1%26%3F%5C%5C2%26%3F%5Cend%7Barray%7D%5Cright%5D)
Now, let's plug in -1 into the equation first to see what we get for y.

-5 is our y if x was -1.
We do the same for the other three numbers.



Step 2:
With all that done, we can now fill out our table and graph the points.

![\left[\begin{array}{ccc}-1&-5\\0&3\\1&11\\2&19\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-1%26-5%5C%5C0%263%5C%5C1%2611%5C%5C2%2619%5Cend%7Barray%7D%5Cright%5D)
If you graph these points on graph paper / a graphing website, you will see that these points go in a straight line. If you are given an ordered pair already (for example: (3,5)), then all you have to do is plug in the x into the equation (3) and see if the outcome is true (5).

Since they don't equal each other, then (3,5) is false.
Here is the graph for the table above. I hope I helped you!
Answer: No
Step-by-step explanation:
2/4 would 1/2 and 14/16 would be 7/8 so no I think
Answer:
6, 8, 10, 14, 15
Step-by-step explanation:
6(1,2,3,6)
8(1,2,4,8)
10(1,2,5,10)
14(1,2,7,14)
15(1,3,5,15)
Answer:
1) x= -1/27
2) x=-4
3) x=13
Step-by-step explanation:
1) 7+7/9x= = -42
14/9x= = -42
14/9x X 9x= -42 X 9x
14= -378x
-378x= 14
-378x/-378= 14/-378
x= -1/27
2) 4x+1=−15
4x+1-1=-15-1
4x=-16
4x/4= -16/4
x=-4
3) −4(x−3)=−40
-4(x-3)/-4= -40/4
x-3=10
x-3+3=10+3
x=13
