When the slope is undefined, you know the line has to be vertical. Vertical lines only have an x in their equations. When you have the coordinates (2,4) with a vertical line, the equation for the slope intercept AND standard form would be the same thing: x=2
If the line is a straight line, meaning 180degrees, it can only have one slope. If it is a function (f(x)= or y=) then the line may have more than one, one, or an undefined slope. Find the first differential of the function and plug in your given x value to find the slope at any given point.
You need either a point and the slope of the line or two points. Then you use the point slope form of the line or the slope intercept form to write the lines.A given point has an infinite number of lines going through it, that is why you need more information.
The slope of a horizontal line is zero. It has a slope, but slope = 0 and this makes it different from a vertical line which has a slope that is undefined because you cannot divide 0 over 0 which is how much a vertical line rises and runs.Ways to find slope:(y2-y1)/(x2-x1 )orrise/run
the slope is the 'm' in y=mx+b so even if the points aren't given, if there is an equation, then you can find the slope. for example, if you have an equation like this: y=2x+5 the slope is 2 and the y-intercept is 5.

The slope for these two points is undefined, or straight up.
y-2 +2 y=2 slope is undefined y intercept is 2
Use point-slope formula
Assuming you mean the slope of a line, not the scope, the slope of a line is determined by its rise over its run. Take 2 points on the line (x1,y1), (x2,y2) and find the slope by plugging it into this equation: (x1-x2)/(y1-y2). If the answer is positive, the slope is positive, if the answer is negative, the slope is negative, if the answer is zero, the slope is zero, and if the answer is undefined (i.e. dividing by zero), your slope is undeifined.

Here are the key steps:* Find the midpoint of the given line. * Find the slope of the given line. * Divide -1 (minus one) by this slope, to get the slope of the perpendicular line. * Write an equation for a line that goes through the given point, and that has the given slope.
