B. y = |2x| - 2.
Step-by-step explanation:
If we start with y = 2x:
this passes through the origin and has a slope of 2.
y = |2x| means the absolute ( positive) values only so the part of the line below the x axis is reflected in the axis to form a V shaped graph.
So we have a V shaped graph with the vertex at (0, 0).
Then -2 brings the vertex from (0, 0) to (0 -2) so we get:
y = |2x| - 2.
