How do you find the slope for (4,2) and (4,5)?

Answer 1

Genesis Allen

The line through #(4,2)# and #(4,5)# is vertical and as such has an undefined slope

The slope for the two points #(x_1,y_1)# and #(x_2,y_2)# is provided by

#m=(Delta x)/(Delta y) = (x_2-x_1)# as well as (y_2-y_1)

if #(x_2-x_1)!= 0#

However, in this instance, #(x_2-x_1) = (4-4) = 0#, and as a result, the slope is not specified.

To find the slope between the points (4,2) and (4,5), you use the formula: ( \text{slope} = \frac{{\text{change in }} y}}{{\text{change in }} x}). Since both points have the same x-coordinate (4), the change in x is 0. Therefore, the slope is undefined.

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.
