Question

Finding the Slope of a Line Use the information provided to find the slope of each line. State what the slope represents. 1 0510 2 025 Seconds Feet Hours Dollars 0 30 60 0 18 45

Answer 1

The slope of line

m = 7.5

Explanation:

Given

`\begin{tabular} X X& Y& \\ 1 & 0& \\ 05 & 30 & \\ 10 & 60 & \\ 2 & 0 & \\ 0 & 18 & \\ 25 & 45 & \\\end{tabular}\end{document}\end{document}`

To find the slope of a line we choose any two value of X and Y

`x_(1) = 1 , x_(2) = 5`

`y_(1) = 0 , y_(2) = 30`

Slope(m) =
`(y_(2) - y_(1))/(x_(2) - x_(1))`

=
`(30 - 0)/(5 - 1)`

=
`(30)/(4)`

= 7.5
