How do you calculate the slope given two points?

Answer 1

Use the slope formula (#m = (y_2 - y_1)/(x_2 - x_1)#) to calculate the slope given two points #(x_1, y_1)# and #(x_2, y_2)#.

Here is an example of finding the slope, given two points (-2,3) and (4,-5).

#(-2, 3) = (x_1, y_1)# #(4, -5) = (x_2, y_2)#

#m = (y_2 - y_1)/(x_2 - x_1)#

#m = (-5 - 3)/(4 - (-2))#

#m = (-5 - 3)/(4 + 2)#

#m = (-8)/(6)#

#m =-4/3#

The slope of of (-2,3) and (-4,5) is #-4/3#

To calculate the slope given two points (x1, y1) and (x2, y2), you can use the formula:

slope = (y2 - y1) / (x2 - x1)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
