Question

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

Answer 1

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

Answer 2

Explanation:

Use the coordinates given in the slope formula:

`m=(y_(2)-y_(1)  )/(x_(2)-x_(1)  )`

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

`m=(-9-(-4))/(15-2)`

which simplifies to

`-(5)/(13)`
