How do you write an equation of a line that passes through (6,6) and has an undefined slope? Can someone please explain how to do this? I don't just want the answer i need to know how to do this please & thank you

OpenStudy (mathmale):

First: A question for you. What does "undefined slope" mean to you? Second question: What does "zero slope" or "a slope of zero" mean to yo u?

OpenStudy (anonymous):

I'm really not sure what undefined slope is. i think zero slope is when the slope is zero?

OpenStudy (mathmale):

Let's look at the concept of slope. What does "slope of a line" bring to mind? If I told you that "the slope of a certain straight line is 1," how would you graph that line?

OpenStudy (mathmale):

Where do you get your primary info about math? online? from a textbook? I am asking you to define SLOPE before we move on to graphing a straight line with a given slope. Please look up SLOPE wherever you get your primary info about Algebra.

OpenStudy (mathmale):

No. That's "distance between two points." Did you actually look up "slope" on the Internet or in a book?

OpenStudy (anonymous):

a surface of which one end or side is at a higher level than another; a rising or falling surface.

OpenStudy (mathmale):

Where did you get that? Please look up "slope" in a MATH book or online ("slope of a straight line").

OpenStudy (anonymous):

i looked up slope on google. In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line.

OpenStudy (mathmale):

Better. It's essential that you understand the concept of "slope" in algebra AND how to calculate or determine what its value is. Slope, in algebra, is the fraction m = rise / run. Have you seen this before? Where?

OpenStudy (anonymous):

yes ive seen it in my online course. i know how to find the equation of a line that passes through a point, i just don't know how to do it when the slope is undefined.

OpenStudy (mathmale):

OK, back to basics. What happens if you divide 5 by zero (0)?

OpenStudy (anonymous):

i didn't think you could divide numbers by zero

OpenStudy (mathmale):

We'd say that 5/0 is "undefined." That's because division by zero is undefined. suppose that your line has an "undefined slope." Using the mathematical formula for slope, m = rise / run, this indicates that the "run" is zero., but the rise is not zero. How would you draw this line?
