(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:
