Help plsss I don’t get it

First off, to write a linear equation or linear inequality, we use the slope-intercept form: y = mx + b, where m represents the slope of a line, and b represents the y-intercept.

The slope of the line is found using rise/run. The rise, in this case, is 3, and the run is 1. 3/1 is 3. So, we can replace the m in the equation with 3 to get:

y = 3x + b

To find b, simply look for where the line crosses the y-axis (vertical line). In this case, it's -3.

The equation you have now is y = 3x + (-3), which is y = 3x - 3.

You're not done yet. A dotted line like here means a point ON the line is not a solution to the equation, so you have to replace the = with < or >. In this case, the shaded region is everything GREATER THAN -3, meaning you use the > (greater than) symbol.

Your final answer is y > 3x - 3.

Hope this helped!

Answer:

Step-by-step explanation:

The other answer should get the Brainliest. Don't neglect awarding it. They are very good to get.

I'm only going to add a graph for you to see. All it does is point out what < and > mean.

As the other responder said, when the boundary is dotted, it is not included in the shaded part.

Also he pointed the difference between < and >. That is what I wanted to address. It is easy to tell.

< is less than the boundary and it is blue.

> is greater than, and it is green.

if the line is solid, then ≤ or ≥ is used.
