Question

Find the slope of the line that passes through (2, 12) and (9, 3).

Simplify your answer and write
as a proper fraction, improper fraction, or integer.

Answer 1

The slope of line is
`-(9)/(7)`.

Explanation:

Given points are;

(2, 12) and (9, 3)

Here,

x1 = 2 and y1 = 12

x2 = 9 and y2 = 3

Slope of a line is given by the following formula;

`m =(y_2-y_1)/(x_2-x_1)\\\\m = (3-12)/(9-2)\\\\m=(-9)/(7)`

Therefore,

The slope of line is
`-(9)/(7)`.
