Choice (B) matches one of these.26 . B
The graph of |f(x)| is the same as the graph of f(x) except that any part
below the x-axis has to be flipped above the x-axis. That’s what choice (B)
shows.
27 . E
Expand both sides and simplify:
Either x = 0 or y = 0.28 . D
The right sides of both inequalities are in mx + b form, so it’s easy to find
the slopes and y-intercepts.
In the first inequality, the slope is 2 and the y-intercept is 3.In the second inequality the slope is (the negative reciprocal of the
other slope, which makes the lines perpendicular) and the y-intercept is
1.All choices have the lines in the right places. The difference is in the
shading. The first inequality has a “greater-than-or-equal-to” sign, so to
