Question

Math help please (will medal and fan)



Solve the following system of equations graphically.

y = 2x - 3
x + y = 3

What is the solution set?

{(2, 1)}
{(1, 2)}
{(-1, -2)}
{(-2, -1)}



Solve the following system of equations graphically.

x + y - 4 = 0
x - y = 0

The solution lies in quadrant _____.

I
II
III
IV

Answer 1

Graph them, then the point of intersection is the solution set.

Answer 2

so for the first one is it the second one

Answer 3

and for the second one is it the third one

Answer 4

I would doubt it since the second point isn't on the first line. I didn't check the second, but if you graph it here I will

Answer 5

oh, so the first one is the first answer

Answer 6

Prove it to me
