A horizontal straight line through #(0,3)# or any other value of #x#.
#y=0x+3#

Explanation:

The equation of a straight line in line #(m)# and intercept #(c)# form is: #y=mx+c#

However, in this example #y# is independent of #x# so the slope is #0#. This equivalent to: #y=3 forall x in RR#

Or: #y=0x+3#

Hence, our graph is a horizontal straight line through #(0,3)# or any other value of #x#.
graph{0x+3 [-6.086, 6.4, -0.7, 5.545]}
