anonymous · Answer

are the slopes the same?

anonymous · Answer

No so there is a solution. They want you to use a calculator. If you don't have one then try graphing it by hand.

anonymous · Answer

yea no calculator

anonymous · Answer

y=1/4x+3
should give you a line like this
|dw:1336932419773:dw|

anonymous · Answer

then graph the other line and try to estimate where the lines intersect.

anonymous · Answer

See what X value they intersect and try to estimate that value and see which one it is closes to from the answers given to you.

anonymous · Answer

I found it its c 8,5

Great good job.
