Question

Solve the system of equations below by graphing both equations with a pencil and paper. What is the solution?

y = 2x - 3
y = -x + 3

A. (0, -3)
B. (1, -1)
C. (3, 0)
D. (2, 1)

Answer 1

Ah, graphing, ok so have you tried anything?

Answer 2

Its undefined.

Answer 3

same thing as before

Answer 4

its D

Answer 5

you got it

Answer 6

Well, I'm not sure how you got that, as your question requires you to graph it out, so why not just graph it out and see :)

Answer 7

there are 2 ways to solve this
one that requires graphing and other that requires substituting options

Answer 8

WHERE ARE YOUR PENCIL AND PAPER?

Answer 9

Mhm, well when you have an equation in the form of y = mx+b to graph it, for example lets take \[y=-\frac{ 2 }{ 3 }x+4\] to graph such an equation, we look at our given values, so y tells us how far up, and x tells us how far along on the following axis. m in this equation represents the slope (how steep the line is) and b is the y - intercept (where the line crosses the y - axis).
So look we have a slope of \[-\frac{ 2 }{ 3 } \implies \frac{ rise }{ run }\] the -2 tells us how far up or down it's going and run is how far to the left or right it is. so you would get something around these lines :p
