Question

Find the slope of the line from the points and the graph.
15. (2,4) and (5, 13)
16. (4,5) and (9,-3)

Answer 1

(2,4) and (5,13) is m=-1/3 and (4,5) and (9,-3) is m=-8/5

Answer 2

Answer:

15. m=3 16. m=-8/5 or -1.6

Step-by-step explanation:

The formula for slope is m=$\frac{y_2-y_1}{x_2-x_1}$

so for #15

$\frac{13-4}{5-2}$=$\frac{9}{3}$=3

and for #16

$\frac{-3-5}{9-4}$=$\frac{-8}{5}$=-1.6
