Question

Do Now:

Mona tried to
solve the
system by
graphing:
x + y = 6
2x - y = 6
What was
Mona's
mistake?
Based on her
graph (shown)
Mona thinks
the solution is
(0,6).

Answer 1

Mona's Mistake: Well, Mona tried to graph something not yet solved.

She should have solved the problems.

x+y=6 Solved is y=-x+6

and

2x-y=6 Solved is y=2x-6

I have also graphed these two points for you, and they intersect at (4,2)

Have a beautiful day, and stay safe.
