Find the slope of the line that passes through points (6,9) and (11,2)

docker41 [41]

Answer:

$-1.4$

Step-by-step explanation:

The slope of a line is the change in the line. It can be found using the formula;

$\frac{rise}{run}$ or $\frac{y_2-y_1}{x_2-x_1}$ .

Substitute in the given points, and solve for the slope;

$\frac{y_2-y_1}{x_2-x_1}\\\\= \frac{2-9}{11-6}\\\\= \frac{-7}{5}\\\\= -1.4$
