Question

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

its in quadrant I

Answer 2

bc you solve by elimination and -y+y=0 so you are left with x+x, which is 2x-4=0, add 4 on both sides of equation and you get 2x=4, then divide by 2 on both sides and get x=2, so actually the solution lies in quadrant I & II

Answer 3

Thank you!!
