7x - 7 ≥ 8 (add 7 to both sides)
7x ≥ 15 (divide to both sides by 7)
x ≥ 15/7 or 2 1/7
All real numbers greater than or equal to 15/7 are solutions.
Graph on a number line all real numbers to the right of 15/7, and use a closed dot to indicate that 15/7 is a solution.

When will the graph of an equation inequality be a dotted line?
The line is dotted when the inequality is a strict inequality, ie it is either "less than" (<) or "greater than" (>). If there is an equality in the inequality, ie "less than or equal to" (≤), "greater than or equal to" (≥) or "equal to" (=) then the line is drawn as a solid line.
How do you solve the inequality and graph a solution?
I think you would use an average two step equation to solve. Graph on a number line. If it was -2, go over 2 to the left, and make a dot. It is hollow or solid. It is solid if there is a line beneath the less than or greater than sign indicating that it is equal to....

How would you know if the endpoint of the graph of an inequality should be a solid dot or open dot?
If the inequality includes 'or equal' then use a solid dot [the value is included]. If it doesn't use 'or equal' then use the open dot.
Why do we represent the solution to an inequality with a graph on a number line but we don't do the same for the solution to an equation?
An equation has an equal sign, which means that we know what the variable is equal to :)
How do you graph the inequality x is not equal to 0?
Very Carefully :)

What do the shaded dots refer to in the graph of an inequality?
The shaded area of the graph of an inequality show the solution to the inequality. For example, if the area below y = x is shaded it is showing those ordered pairs which solve y < x.

How do you graph and solve the system of inequality -3 is less than x and x is less than or equal to7 on a ti-83 calculator?
You open your Apps, which should be the purple button, and then you open inequalz, from there you can put in your inequalities and then hit graph and it will come up on screen.
Is it possible for the graph of an inequality to consist of only one number?
No it is not if you have a single inequality. It you had a single point as the solution, then it effect you would have an equality. If you have x> or equal to 1 and x< or equal to 1 then the graph is the single point 1. So it is possible with systems of inequalities.
What is the definition of graph of an inequality?
