What is the slope of the line below? If necessary, enter your answer as a

alisha [4.7K]

Step-by-step explanation:

Use formula to find the slope/gradient

$\frac{y2 - y1}{x2 - x1}$

(-5, -1) = (x1, y1)

(5, 11) = (x2, y2)

So,

$= \frac{11 - ( - 1)}{5 - ( - 5)} \\ = \frac{12}{10 } \\ = \frac{6}{5}$
