Yes, the slope can be a fraction; and can be less than one or negative.

The slope is the rise over the run, like a fraction. Rise is the numerator, run is the denominator. That gives you a fraction. Then just divide if you want a number.

yes, slope can be fraction. It's like -1, -1/3 , 4/5 , 4 and so on.

To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of 3 can be written as 3/1. The slope of a line that is perpendicular is -1/3.

To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of a line that is perpendicular to a line with a slope of -2/3 is 3/2, (or 11/2 or 1.5).

Why not? m=4/3 is a perfectly good slope

The equation for slope = rise / run

Only if it happens to BE a whole number. As you probably know, you can't "convert" a fraction to a whole number, without losing precision. But the slope may well happen to be a whole number, such as 1, 2, 3, -1, etc. (or close enough to a whole number).

It is simply the arctan transformation of the fraction.

Slope of vertical and horizontal linesThe slope of a vertical line is undefined. This is because any vertical line has a x or "run" of zero. Whenever zero is the denominator of the fraction in this case of the fraction representing the slope of a line, the fraction is undefined. The picture below shows a vertical line (x=1)The slope of a horizontal line is zeroThis is because any horizontal line has a . Y or "rise" of zero. Therefore, regardless of what the run is (provided its' not also zero!), the fraction representing slope has a zero in its numerator. Therefore, the slope must evaluate to zero. Below is a picture of a horizontal line...you can see that it does not have any 'rise' to it.Formula to find the slope of a lineExample 1of the Slope of A lineThe slope of a line through the points (1, 2) and (2, 5) is 3 because every time that the line moves up three (the change in y or the rise) the line moves to the right (the run) by 1.Illustrated Example TwoThe slope of a line going through the point (1,2) and the point (4,3) is 1/3.

The slope is the rise/over run of a line. The equation of a line is usually written in the form y=mx+b where m is the slope and b is the y-intercept. To find the slope, you can take two points on a line, find how much the line goes up (or down) between the two, and divide it by how much the lines moves to the right. Usually the slope is left in the simplest fraction form.

You find the tangent to the curve at the point of interest and then find the slope of the tangent.

You find the slope of the tangent to the curve at the point of interest.

Yes

It is the change in y divided by the change in x.

The same rules apply but it might help if you turn the fraction into a decimal.

y=7/3x-13

If the slope of a line is m then the slope of an altitude to that line is -1/m.

Of course. If the line rises 18 units for every 27 horizontal units,then its slope is 2/3 .

Why do we need to find the slope of a line? The slope of a line tells us how something changes over time. If we find the slope we can find the rate of change over that period.Why do we need to find the slope of a line?The slope of a line tells us how something changes over time.

You have to find the slope and y-intercept first.

Use point-slope formula

You have to differentiate the equation. The dy/dx is the slope.
