I'm willing to fan and medal.

A pair of equations is shown below.

3x − y = 9
y = −2x + 11

If the two equations are graphed, at what point do the lines representing the two equations intersect?

(4, 3)
(3, 4)
(9, 11)
(11, 9)

Just a bit confused ;-;

lynfran · Answer

3x-(-2x+11)=9
3x+2x-11=9
5x=9+11
5x=20
x=20/5
x=??

lynfran · Answer

whats 20/5=??

anonymous · Answer

Four.

lynfran · Answer

good x=4
so when x=4 
y=-2(4)+11
y=-8+11
y=??

anonymous · Answer

19 ofc

lynfran · Answer

no -8+11=?? it can also be written as 11-8...??

anonymous · Answer

Whoops, didn't see the negative sign.

That would be three.

THey would intersect at (4, 3) correct?

lynfran · Answer

correct
