Which graph is linear? Absolute value function graphed on a coordinate plane. The graph goes through negative 2 comma negative 1, negative 1 comma negative 2, its vertex 0 comma negative 3, 1 comma negative 2, 2 comma negative 1. A line graphed on a Coordinate plane with x axis ranging from negative 5 to 5 and y axis ranging from negative 7 to 3. The line passes through begin ordered pair 4 comma negative 2 end ordered pair and begin ordered pair negative 4 comma negative 4 end ordered pair. Graph of an exponential function on the coordinate plane. The horizontal axis ranges from 0 to 12 in increments of 1. The vertical axis ranges from 0 to 12 in increments of 1. The curve passes through begin ordered pair 0 comma 5 end ordered pair, begin ordered pair 2 comma 5.44 end ordered pair and begin ordered pair 6 comma approximately 7 end ordered pair. I don't know.
