Jeremiah recorded his checking account balance each month on a graph for a year. If x represents the month and y represents his bank balance, which scenario would result in the graph having an x-intercept?

OpenStudy (jusaquikie):

you need to attach a copy of the graph or draw it please.

OpenStudy (kewlgeek555):

It doesn't have one...

OpenStudy (kewlgeek555):

Only has the options.

OpenStudy (jusaquikie):

ok draw a axis with an x on the bottom and a y on the side

OpenStudy (kewlgeek555):

Okay.

OpenStudy (jusaquikie):

x represents the month but the line that sits above it represents what?

OpenStudy (kewlgeek555):

the money he has in his bank account?

OpenStudy (jusaquikie):

now what does it mean to cross the x axis?

OpenStudy (jusaquikie):

that happens to y if it is below the x axis?

OpenStudy (kewlgeek555):

x-intercept.

OpenStudy (jusaquikie):

what kind of a y would be below the x axis?

OpenStudy (kewlgeek555):

y-intercept?

OpenStudy (jusaquikie):

don't think in intercepts at this time lokk at this

OpenStudy (jusaquikie):

OpenStudy (jusaquikie):

below the axis it starts negative numbers, so what would cause his balance to be negative?

OpenStudy (jusaquikie):

all an intercept is is the point that it crosses the axis, if it's a x intercept it means that the x value is 0, if it's the y intercept it means the y value is zero,

OpenStudy (jusaquikie):

since this problem is based on a bank account the only time that you can have negative money is when you bounce a check. or overdraw your account.

OpenStudy (jusaquikie):

well the other option is if he had no money in his accoun then it would be zero which would put the y value to zero which is on the x axis.
