Are the following linear equations?
y = xz
y = |x|
y = 2^x
Linear format y=mx+b (Linear= LINE)
The second option is an absolute value graph, in which the graph would look like a “V” on a graph
The Third Option is similar to a quadratic y=ax^2=bx+C, which would look like a “U” graph.
The first option??? - Should be the correct answer if Z is the slope and x is your coordinate, for instance, y=2x, The slope is 2 and your y-intercept is 0.
The first is not really linear, no. y = x + z is, not y = xz. Degree is not 1.
