What is the slope of the line passing through the following points: #(-9,1) , (-19,12)#?

Answer 1

Avery Alexander

#-11/10#

To find the slope using two points divide the difference of the y-coordinates by the x-coordinates:

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

#(12-1)/(-19-(-9))#

#11/(-10)#

#-11/10#

To find the slope of the line passing through the points (-9, 1) and (-19, 12), you can use the slope formula:

slope = (change in y) / (change in x)

Substitute the coordinates of the two points into the formula:

slope = (12 - 1) / (-19 - (-9))

Calculate the changes in y and x:

change in y = 12 - 1 = 11 change in x = -19 - (-9) = -19 + 9 = -10

Now, divide the change in y by the change in x:

slope = 11 / (-10)

So, the slope of the line passing through the points (-9, 1) and (-19, 12) is -11/10.

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.
