Question

College Algebra: I'm doing 2X2 Non-Linear Systems and I'm stuck on a math problem. I need to solve this system algebraically and then graph both of the equations on the same coordinate system to support my solution. The problem is:
y-x=3
y=|x|

Answer 1

graph both, the intersection point is the solution

Answer 2

or point(s)

Answer 3

y = 3+x
so at x = 0, y = 3. Thus we get (0,3) as first point
similarly find few more values

y= |x|
for x = 0, y = 0. Point (0,0)
for x = 1, y = 1. Point (1,1)
for x= -1, y = 1. Point (-1,1)

Answer 4

Answer 6

So, the first point is (0,3)

Answer 7

yeah

Answer 8

Okay, that's the first line on the graph. I also graphed the rest of the points and got a right side up V

Answer 9

Wherever it intersected, that's the answer correct?

Answer 10

It intersected at (-1.5, 1.5)

Answer 11

correct. That is the solution

Answer 12

Thank you very much! I appreciate it. :)
