Respuesta :

The two linear equations are y=x/2 and y=2x-5.

They are linear because they are of the form y=mx+b.  y=x/2 can be written as y=1/2x or y=1/2x+0.

y=2ˣ is an exponential function, since x is the exponent.  It will graph as a smooth curve instead of a line.

y = x²+6 is quadratic since the highest power of x is 2.  It will graph as a parabola, or u-shaped graph.
