Choose the system of equations that matches the following graph.
@Luigi0210 @Mertsj
What is the solution of the system shown in the graph?
What do you mean
3 ways to solve it that I know of: 1. Solve each equation algebraically and see which matches the solution pair 2. Graph each and see which is the best fit 3. Just do what Mertsj said and locate the ordered pair, plug back in and see which gives a true statement c:
The point where the lines cross is the solution.
do they cross at -3?
An ordered pair has an x and a y value.
-6, -3
(-6,-3) is correct. Now replace x and y with those values in each of the answer choices until you find the one where both sentences are true when you put in those numbers.
How exactly do I do that...? :c sorry if I'm bothering you..
Do you see the equation 2x+4y=0 ???
It is the first equation in the first answer choice.
Yes
In the ordered pair (-6,-3) which is the x value?
-6
So in the equation 2x+4y=0, replace x with -6 and replace y with -3. Does that make a true statement?
no it doesn't
Then move on to answer choice 2 and do the same thing.
would it be the third one
Hang on...I'll check
Good job!!! That one works.
Thanks for the help!
You're most welcome.
