If point a has coordinates (x1,y1), and point b has coordinates (x2, y2), then the slope of the line is given by the formula:
m = (y2-y1)/(x2-x1).

The slope of line ab is 3 what is the slope of line CD if CD is parallel to ab?
3
How do you find slope altitude?
If the slope of a line is m then the slope of an altitude to that line is -1/m.
How do you find the slope of a line parallel to another line?
The slope of both lines will be the same.
The slope of line a is 3 what is the slope of a line perpendicular to a?
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.
What does a zero slope line look like?
A straight, horizontal line.
The slope of line ab is 3 what is the slope of line CD if CD is parallel to ab?

Suppose the slope of AB is zero what is the slope of CD given that a. CD is parallel to AB b. CD is perpendicular to AB?
Any line that is parallel to another line will have the same slope. So if line AB's slope is zero and line CD is parallel to AB, then its slope will also be zero. The slope of line CD, when perpendicular to AB, will be infinity. If line AB has a slope of zero that means its just a horizontal line passing some point on the y-axis. A line that is perpendicualr to this one will pass through some point on the x-axis and therefore have an infinite slope.
If AB is parallel to CD and the slope of CD is one over two what is the slope of AB?
The slope of line AB will be 1/2. Two parallel lines will always have the same slope, so if you know the slope of one line that is parallel to another, you know the other line's slope.
Slope of a line AB is 4 what is the slope of CD if CD is perpendicular to AB?
Slope of perpendicular line is the negative reciprocal. So it is -1/4
If line AB contains the points 4 19 and -3 5 what is the slope of a line perpendicular to AB?
-1/2 or -0.50
If AB contains the points 6 -2 and -3 16 what is the slope of a line perpendicular to AB?
0.5
How do you find slope altitude?
If the slope of a line is m then the slope of an altitude to that line is -1/m.
How do you find the slope of a parallel line?
Parallel lines have the same slope. So if you know the slope of a line in question, or you can calculate it, then you know the slope of any line parallel to that line.
How do you find the slope of a line parallel to another line?
The slope of both lines will be the same.
How do you find a slope in a line?
the slope of a line = the Change in Y divided by the Change in X
How do I find the slope of a line?
you look at the line and see if there are any direct points on the line the slope formula
What does the slope examples of rates inclued?
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.
