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

1 Answer

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
