Question

ANGE FROM TWO (X,Y) VALUES.

9. Find the slope of the line
that passes through (10,8)
and (9, 13).​

Answer 1

The slope of the line that passes through (10,8) and (9, 13) is – 5

Solution:

Given, two points are (10, 8) and (9, 13)

We have to find the slope of a line that passes through the above given two points.

Slope of a line that pass through
`\left(\mathrm{x}_(1), \mathrm{y}_(1)\right) \text { and }\left(\mathrm{x}_(2), \mathrm{y}_(2)\right)` is given as:

`\mathrm{m}=(y_(2)-y_(1))/(x_(2)-x_(1))`

`\text { Here, in our problem, } x_(1)=10, y_(1)=8 \text { and } x_(2)=9, y_(2)=13`

`\text { slope } m=(13-8)/(9-10)=(5)/(-1)`

`=(-5)/(1)=-5`

Hence, the slope the line that passes through the given points is – 5
