Hello there!
First, we need to know when do we have a linear equation.
<span>"A linear equation is an equation between two variables that gives a straight line when plotted on a graph."
I am honestly not good with graphing these kind of equation, so I usually used an online graphing to help me.
Remember we have a linear equation when we have straight line.
Graph the first equation(see picture 1) Y = 4/x + 3
Answer: No, it is not a linear equation. As you can see the lines are not straight. Got it? I hope so :)
P.S Unfortunately, I am not sure what is happening but I can load the pictures of the graph. So here is the link to the graph for the first equation.
Now let's work with the second equation y = -2x - 4
Answer: Yes it is a linear equation. Why? Because the line is straight. See this link for the graph.
I tried my best, I hope you understand and if you have questions, just let me know.
As always, I am glad to be your helper!

Answer:
30
Step-by-step explanation:
30/3 = 10
30/10 = 3
30/15 = 2
Hope this helps!
Answer:
C. y = -1/3 + 1
Step-by-step explanation:
Parallel equations have the same slope.
Answer:
A square that has sides of 4.5 units, or a rectangle that is 1 unit wide and 8 units long.
Step-by-step explanation:
First, you need to find the perimeter in the first place. Since there are two sides of the same number, you would double each number.
2 would become 4
6 would become 12
Add 4+12=18
So, our rectangle has to have a perimeter of 18 units. Because a square is a rectangle, you can divide 18 and 4, since a square has 4 sides. You get 4.5. Each side can be 4.5 units.
Or, you can have a rectangle. What I thought first was a length of 9, but I knew that wouldn't work. I drew a rectangle and tried 8. If I put it on the top and bottom, which you need to to find the perimeter, it was only 16. Then I knew I could use 1 as a side length. If you added the sides, it would equal 2, and when you add 16 and 2, it's 18. So, you can use a rectangle that has a length of 8 units and a width of 1 unit.
