Question

A line passes through the points (1,2) and (3,1) what is the slope of the line

Answer 1

The slope is -1/2.

Explanation:

Slope formula:

`\displaystyle (y_2-y_1)/(x_2-x_1)`

`\displaystyle (1-2)/(3-1)=(2)/(-1)=-(1)/(2)`

`\Large\textnormal{Therefore, the slope is -1/2.}`

Answer 2

-1/2

Explanation:

The slope of a line is given by

m = (y2-y1)/(x2-x1)

= (1-2)/(3-1)

= -1/2

The slope is -1/2
