Hello there!

First, we need to know when do we have a linear equation.

"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
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

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!

1. No, its not a linear equation.

2. Yes, it is a linear equation.

A load of linear equations are in the format of "mx+b". If you find a number that's divided by x, it most likely is non-linear.

the most boring ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
