Question

Plzzz help don’t understand plz explain

Answer 1

So the easiest way to do this problem is to put your equation in linear form, meaning y = the rest of the equation.

I'm going to show the work to do that below:

2x - y = 4

-2x -2x (Here I am subtracting 2x)

- y = 4 - 2x

(-1)(- y) = (-1)(4 - 2x) (Now I'm multiplying both sides by -1 to make y positive)

y = 2x - 4 (And just for neat purposes I'm going to put the 2x in front of the 4)

Now you have your equation ( y=2x-4 ) and you're ready to put it on the points of your graph.

Start on the point (0, -4) to represent the y axis.

y = 2x - 4

Then, your rise (2) over your run (1)

so your coordinates for a line will be:

(0, -4) (-2, 1) (1, 0)

You only need to plot these three to connect your line.

I appologize for my lack of visuals i understand this might be confusing, however if you have any further questions feel free to let me know!
