How do you solve and graph 8 x > 7 x − 4 ?
Explanation:
Subtract 7x from each side of the inequality to solve for x while keeping the inequality balanced:
To graph this we will draw a vertical line at −4 on the horizontal axis.
The line will be a dashed line because the inequality operator does not contain an “or equal to” clause.
We will shade to the right side of the line because the inequality operator also contains a “greater than” clause:
