Question

Solve the system 2x + 3y = 3 and 3x – 2y = 11 by using graph paper or graphing technology. What is the solution to the system?

a. (–3, 3)

b.(–1, –7)

c. (1, –4)

d. (3, –1)

Answer 1

You should rearrange the formulas into y=mx + b form and the graph them on the same graph. The point where the intersect is the solution to the system. Do you know how to do this?

Answer 2

If you have a graphing calculator rearrange the formula for y=mx + b and plug into the calculator same deal look for the intersection. You could also solve like this
3/2(2x+3y = 3) is 3x + (9/2)y = 9/2 then subtract second equation from first to get
3x + (9/2)y = 9/2
-3x - 2y = 11
becomes 13/2y = -13/2
y = -1
3(x) - 2(-1) = 11 so x = 3
So you answer should come out to d. (3,-1)

Answer 3

You could also find an online graphing application that allows you to graph to things simultaneously.

Answer 5

@mathdood (<-nice), can you explain to me a lil more how you got that answer.. like where the fudge monkeys that 9 came from lol
