Question

Is y = 4/x + 3 a linear equation?
is y = -2x - 4 a linear equation?

Answer 1

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.

Answer 2

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
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!
