Question

How do I find the slope of a line.

Answer 1

you get two coordinate points from the line. subtract the y values and divide it over the difference of x values.
formula:
y2-y1/x2-x1

Answer 2

To find the slope of the line we must know two of the points on the line.
Then we use the slope formula to find the slope
y2 - y1
---------
x2 - x1
