What is the slope of the line passing through the following points: # (1,5) ; (-8,8)#?

Answer 1

Eli Assouline

#m=-1/3#

#m=(y_1-y_2)/(x_1-x_2)# #m=(5-8)/[(1-(-8))# #m=-3/9# #m=-1/3#

To find the slope of the line passing through the points (1,5) and (-8,8), we use the slope formula:

[ \text{Slope} = \frac{y_2 - y_1}{x_2 - x_1} ]

Substituting the coordinates of the points into the formula:

[ \text{Slope} = \frac{8 - 5}{-8 - 1} ]

[ \text{Slope} = \frac{3}{-9} ]

[ \text{Slope} = -\frac{1}{3} ]

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.
