Question

what is the slope and y intercept of 
y=5?

anonymous · Answer

@johnweldon1993 I am confused, so is the slope 0, and y intercept 5?

yrelhan4 · Answer

yes..

anonymous · Answer

ok and for the next problem I am suppose to find the slope and y intercept of x=-7

anonymous · Answer

so how would I do that?

yrelhan4 · Answer

you could imagine it like this.. what is slope? like how much the line is inclined.. plot x=-7.. its a vertical line right? what should be the slope? infinity.. 
as the question is asking for y intercept.. it is 0.. the line does not intersect the y axis, the question of y intercept doesnt arrive..

as a general rule for slope.. for a line ax+by=c.. the slope if -b/a ..

anonymous · Answer

oh so the slope is infinity because the y intercept is 0?

yrelhan4 · Answer

and pardon me.. slope=-a/b .. 
and yeah you can imagine it like that. but a more logical approach would be how much it is inclined. |dw:1370962926783:dw|

anonymous · Answer

wait so a slope can equal infinite?

yrelhan4 · Answer

theoretically, yes.

anonymous · Answer

or would it just be undefined?

yrelhan4 · Answer

its how you like to call it. both are fine..
