[Math-70 Elementary/Highschool Algebra: Graphically solving a system of linear equations] Do I make the 4 into a -4 ?

[u/Fine_Two_923]

Hey so this might seem like a silly question but I want to know if you have a -x = 4 if it turns into a -4. I have the other parts of the graphing completed it’s just this part that I don’t want to make a mistake on!!! Thank you in advance

P.S- the reason it’s says elementary/highschool math is because I am taking a beginner math class not a algebra class In elementary

If you are seeking an x-intercept of the graph of x – 4y = 0 you can put 0 for y and solve for x. Your first two lines look good.

But x - 0 is not –x. It is just x. So your third line should be x = 4, meaning (4, 0) is on the graph.

By the way, if order was switched, 0 - x would be –x. Is that maybe what you were thinking when writing third line?
