# How to write an undefined slope

In the third year there were 57 participants. The answer is the slope is 2 and the y-intercept is However, most times it's not that easy and we are forced to really understand the problem and decipher what we are given.

Divide the difference of the y-coordinates by the difference of the x- coordinates: When m gets smaller, the slope flattens.

The standard point slope formula looks like this: JustAnswer in the News: If the slope is undefined, it is a vertical line. Here you will have to read the problem and figure out the slope and the point that is given. In this case it denotes a specific y value which you will plug into the equation.

Then we can write our equation. Set a, b and c to some values. So far you have the y, m, and x. Slope Intercept Formula The graph below represents any line that can be written in slope intercept form. Your point is -1,5. Locate the x and y intercepts and compare with the solution above.

Once you have m slope and b y-interceptyou can write an equation in slope intercept form. This type of linear equation was shown in Tutorial How is the x-intercept represented in the slope intercept form of a linear equation.

Well you know that having a 0 in the denominator is a big no, no. The point I've indicated, -1,0just happens to be the easiest one to find. If a line is vertical the slope is undefined (see below). The rise of a road between two points is the difference between the altitude of the road at those two points, say y 1 and y 2, or in other words, One can then write the line's equation, in point-slope form.

A line with undefined slope is a vertical line. Computing the slope would involve division by zero, which is why the slope is undefined.

A typical equation for a vertical line is [math]x = a[/math], where [math]a[/math] is any constant. If every slope is a fraction, then the rise (or y-values) is your numerator and the run (or x-values) is your denominator.

For example, slope=3/2 rises 3 units and goes right 2 units. An undefined slope can be thought of as a fraction, which is also a division problem. There must be a zero in there somewhere.

Because it possesses an undefined slope, x must always equal the x intercept, a value that remains constant, in the equation. Now to actaully solve. We're trying to fill in the blank in x=_ Since the x value of the point is 2 and the x value always remains constant, the x value is 2. A line with undefined slope is a vertical line. Computing the slope would involve division by zero, which is why the slope is undefined. How do you write an undefined slope?

Update Cancel. ad by Truthfinder. Locate anyone by entering a name, it's that simple. A popular site reveals data on millions of Americans. Two easy steps: enter name. An undefined slope results from a vertical line, which has multiple x coordinates but no y coordinates. To solve for the slope of a line, it is necessary to select two points and divide the difference in y coordinates from the difference in x coordinates.
