Depdns on what you mean be intersect - if they are directly on top of each other?
so then sometimes?
thats all the ? ask's
Well, ask your teacher if he/she means intersect as in on top of each other. Techincally two line equations that are on top of each other can be shown to be the same equation. But, we can still call them two functions that are exactly equal, and in this case that have an infinite amount of intersections. If lines on top of each other don't count, then the answer is never - that is, if the line was straight. I hate probems like this (not you, the problem xD) because they are way to ambiguous.
is that an "in", or an "at"?
My class there is no teacher its all online So the teacher just sits at his desk and i can't ask him a question he pretty much just sit on his retriceall day or going threw his play book because hes a coach
B. sometimes. depends on the lines. refer the 3 cases below |dw:1332419161455:dw| |dw:1332419227159:dw| |dw:1332419282400:dw| in the last case, the line s are coincident that is they are basically the same line,so the have infinite solutions ofcourse!! eg.- 2x+3y=4 and 4x+6y=8. see if you can find something common to the two!
Just say sometimes, and if the you get the question wrong, then talk to your teacher about the lines. If he tells you that they are the same line, he's wrong. If he does, respond that they are different, yet equivalent functions, and thus (f(x)=mx+b, g(x)=mx+b).
Two lines intersect in more than one point. Never within the context of a high school Geometry course. Final Answer: Never. --- Note: Now, I have to find where I should have posted the other answer.
Directrix, the problem is, THEY ARENT STRAIGHT LINES TROLOOLOLOLOLOL
and if it's "in", it's never. if it's "at", it should be sometimes.
