How can i put y=7 into slope-intercept form?

Question

dangerousjesse · Answer

The line $y=7$ is equal to 0. thus, any "x" multiplied to "0" equals 0 and the term drops off the slope intercept form..

aum · Answer

y = 7 is the equation of a horizontal line parallel to the x-axis.
The slope is zero.  Threfore, in y = mx + b, m = 0 and so y = b. Here y = 7.

anonymous · Answer

so there is no way to answer this? what if it was x=7?

dangerousjesse · Answer

Then there's still no possible slope..

aum · Answer

For the first one:  y = 0*x + 7  is the slope-intercept form of y = 7.

aum · Answer

It is not possible to put x = 7 in slope intercept form because x = 7 is a vertical line and therefore the slope is infinity or undefined.

anonymous · Answer

ok, i see! so because there is no m, it screws everything up. so slope is 0 and the y intercept is 7

aum · Answer

yes, for the first one.

anonymous · Answer

ok, what about for x=-6? (sorry, i just started algebra 2 today)

aum · Answer

same answer as the previous question for x = 7.

It is not possible to put x = -6 in slope intercept form because x = -6 is a vertical line and therefore the slope is infinity or undefined.

aum · Answer

Slope of a horizontal line parallel to the x-axis is zero.
Slope of a vertical line parallel to the y-axis is undefined.

ok thanks! I'm a freshman and my class is with sophomores and juniors @o@

aum · Answer

You are welcome.  Are you taking advanced math?

anonymous · Answer

I guess you could call it that. Im in Algebra 2 honors because i took Geometry over the summer!

aum · Answer

cool.  Do well.
