Question

Determine the slope of the line passing through the points (2,-4) and (15,-9).

Answer 1

Answer:

Step-by-step explanation:

Use the coordinates given in the slope formula:

$m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }$

Our y2 is -9, y1 is -4, x2 is 15 and x1 is 2

$m=\frac{-9-(-4)}{15-2}$

which simplifies to

$-\frac{5}{13}$

Answer 2

The slope is equal to negative 5 over 13 (-5/13).
