That is how the absolute value is defined. For x < 0 the value of x is negative (by definition). Therefore, the value of negative x is positive (negative of a negative). So abs(x) = -x when x < 0

No, because 'x' is a variable.
The answer will depend on what x is.

180-x...... hahaahahaaa
The formula to find the value of X would be Y-2X. This would equal to y-9 times 2 X.

You look for the value of 0 in the y column, and find out what x has to be for y=0. This value of x is you x-axis intercept. (Reverse "x" and "y" in the above description to find the y-intercept, if there is one).

if y = 5x – 8 find the value of x if y = 7
