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

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 of a line on a graph can be zero, or any positive or negative real whole number or fraction or decimal.
Points: (1, -2) and (3, -5) Slope: -3/2
The line perpendicular to a line with a slope of 1/5 has a slope of -5.
