Why u have so much letters lol what u need help on
The domain and range for each line is all real numbers. This is because all numbers are possible to input into x and all y values exist.
The slope of the first line is -2/3 and the y intercept is 6. You can reach this conclusion by solving for y (putting it in slope intercept form).
The slope of the second one is 3/4. and the y intercept is all real numbers greater than -4. This is true because it is an inequality and you can find these numbers by solving for y.
76 is the mean for this problem
I'm guessing to probably divide $45,000 by 23 and then multiply that answer by $12,000. I hope this helps
The line cuts the X axis at 
and is parallel to the Y axis.
Thus the equation of the line is $\boxed{x=3}$
