Answer:

(see below)

Explanation:

#y=2x-3# is in slope-intercept form with
#color(white)("XXX")#slope of #2# and
#color(white)("XXX")#y-intercept of #-3#

A y-intercept of #-3# means that we have a point on the line at #(0,-3)#

A slope of #2# means that for every #1# unit we move in the positive #x# direction, the corresponding point on the line will go up #2# in the positive #y# direction.

Therefore we can deduce the points:
#color(white)("XXX")(0,-3)#
#color(white)("XXX")(1,-1)#
#color(white)("XXX")(2,+1)#
#color(white)("XXX")(3,+3)#
and so on.

Plotting these point and drawing a line through them should give you a graph like:
