you evalutate the expression at each value of x and that gets you the value of y.

your equation is y = abs(x) - 4

you just substitute the value for x in the equation and solve for y.

for example:

when x = -3, y = abs(-3) - 4 = 3 - 4 = -1

when x = 3, y = abs(3) - 4 = 3 - 4 = -1

all you do is substitute the value for x in the equation that involves x.

x is the independent variable which means you choose the values of x.

y is the dependent variable which means the value of y depends on the value of x.
