Line H is represented by the following equation: 2x + 2y = 8

What is most likely the equation for line K so the set of equations has infinitely many solutions?
x + 2y = 2 x + y = 4 2x + y = 6 x − y = 8

if they all have infinite many solutions then wouldnt that make them all the same line? @lil_chukie

anonymous · Answer

so rewrite every option they have into slope-intercept form

OK

anonymous · Answer

im going to solve it, then lead you to the answer, it may take a min.

anonymous · Answer

Ok, there is an answer to the problem!

anonymous · Answer

Since 2x+2y=8 and x+y=4, what do you notice about the two equations?

anonymous · Answer

ok, so 2x+2y=8 and x+y=4 have the relationship of the line being the same. Divide all the terms on both sides of 2x+2y=8 and you will get x+y=4!
