It means that the numeral is to be multiplied by a thousand. For example, X = 10 but with a line over X it would be 10,000. A horizontal line above a numeral means that it should be multiplied by a thousand so VII with a line above it represents 7000, it can also be written as (VII)
my but
(X) or X with a line above it
The graph of y = x + 1 is a straight line with slope 1 which passes through the point (0, 1) If you have y < x + 1, then it is the area under the line y = x + 1 and is shown by shading the area under the line. If you have y > x + 1, then it is the area above the line y = x + 1 and is shown by shading the area above the line.
The graph of y > - x is an area, firstly draw the line y = -x which is a line sloping diagonally upwards to the left at 45o and the area where y > -x is the area above the line

(mean x, mean y) is always on the regression line.
It is: (X) or X with a line above it the brackets or line indicate multiplication by a thousand so 10*1000 = 10,000
Mark a point on the x-axis as 's', then draw a solid line through this point, with a slope of 1. Then shade in the area above this line. The region above the line is shaded because if x-s < y then y > (x-s). The line is drawn as a solid line to represent that it can be equal, as well. At the point x=s, y = 0, which is where you marked s on the x-axis.
The x on the horizontal line is used as a reference point. You have a grid. You have a horizontal line and a vertical line. You have two reference points, your x axis and your y axis. In algebra, you search for the point or points where your function crosses the x axis. In calculus, you search for the points where your function changes direction. In advanced geometry, you search for the slope for the slope for the function. As far up or down as you can go, each place on your paper is above or below one point of the horizontal line and can given an x address referring to a point on that line. if you are a million lines out on the x line, your location is 1,000,000x. Your Y line gives you an address as to how high you are above or below the x line. if you are two lines above the x line your y address is 2y. So at that point your function has an address of 1,000,000x, 2y. Everyone knows where the function exists at that point.
If you mean the slope of the line with equation y = x then it is 1 and there is no y intercept

The line above the number means in Math Terms that the number is repeditive and goes on and never stops.
