Question

An Email to the Editor Your favorite math magazine has recently published an article on their website about whether solving systems of non-linear equations is easier by graphing or algebraically. You decide to write an email to the editor of the math magazine defending your opinion. Your email must be two to four paragraphs in length. You must express your opinion on which method is easiest. Provide at least three pieces of supporting evidence. Provide an additional graph of a system of non-linear equations that supports your viewpoint.

Answer 1

I'm not going to write the essay for you, but I will tell you my stance on the issue:

When you're graphing two lines, you may think you see the exact point at which the lines intersect, but your eye is fallible. What may look like the point (5,16) may actually be (5.05, √254). Also, two graphs may look like they don't intersect, but if you extended the graph, you may see the point(s) of intersection. Additionally, your ruler may slip when you're drawing the parabola through points (2,7) and (-10, 3) so that it's just tenths of a degree off from the real line.

Whenever you graph, you're only getting an approximation. It's better to use algebraic methods, because ordinal numbers (not measurements) are always intended to be precise. All you have to do is add, subtract, divide, and multiply. 8-5 will always be 3. Never 3.005, never √8.75 Hope that helped a bit...
