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.
