What is the slope of the line passing through # (9,9);(-11,7) #?

Answer 1

Eva Adamson

The formula for the slope of a line is m = #(y_2 - y_1) / (x_2 - x_1)#

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

m = #(7 - 9) / (-11 - 9)#

m = #-2/-20#

m = #-1/10#

To find the slope of a line passing through two points, you can use the formula: ( \text{slope} = \frac{{\text{change in } y}}{{\text{change in } x}} ). Substituting the given coordinates, we get: ( \text{slope} = \frac{{7 - 9}}{{-11 - 9}} = \frac{{-2}}{{-20}} = \frac{{1}}{{10}} ). So, the slope of the line passing through the points (9,9) and (-11,7) is ( \frac{{1}}{{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.
