Question

How do you graph the inequality `7x+1<15`?

Answer 1

`x<2`

To graph, we place a hollow dot around 2 (to indicate that it is not a part of the solution) and a ray heading off to the left (towards 0 and negative numbers).

Explanation:

`7x+1<15`

`7x+1color(red)(-1)<15color(red)(-1)`

`7x<14`

`(7x)/color(red)(7)<14/color(red)(7)`

`x<2`

To graph, we place a hollow dot around 2 (to indicate that it is not a part of the solution) and a ray heading off to the left (towards 0 and negative numbers).
