Please see below.

#y=2x-3#

Because both #x# and #y# have power of #1#, this is the equation of a straight line. We identify two points on the line and connect them together.

The easiest way to do this is to plug in #0# foe #x# and solve for #y#. Then plug in #0# for #y# and solve for #x#:

#x=0, :. y=-3# Point #(0,-3)# is a point on the line.

#y=0, :. x=3/2=1.5# Point #(1.5, 0)# is a point on the line.

Let's locate these two points on the #xy# coordinate system and connect them together:
