A line has a slope of -3/7 and its y-intercept is (0,18). What is its x-intercept?
You can find the equation of the line. y=-3x/7+b. Plug 0,18 in you get b=18. y=-3x/7+18, so y=0 the 3x=18*7 so x would be 42. (42,0)
I have already answered this question a few hours ago. If you just want answers then don't bother to learn. You obviously just want to cheat and not understand anything.
If you want to be like this then sure go ahead you won't get very far in life.
