Question

What is the slope of the line that passes through the points (5, 4) and (13.25, -18) ?

A.) 83/3

B) 3/8

C) −3/8

D) 8/3

Answer 1

Answer: D. 8/3

Explanation:

Formular for slope:

[ consider points (x1, y1) and (x2, y2) ]

`slope = (y_(2) - y _(1) )/(x _(2) - x _(1) ) \\`

x1 » 5, y1 » 4

x2 » 13.25, y2 » -18

`sloe = ( - 18 - 4)/(13.25 - 5) \\ \\ = (22)/(8.25) \\ \\ { \boxed{ \boxed{slope \: = (8)/(3) }}}`
