Assuming you mean:
y = 2x +3
Then you can compare this to the slope-intercept form:
y = mx + b
m = slope
y-intercept = (0,b)
The slope is 2. The y-intercept is (0,3).
Then you only need one more point to be able to draw a line.
A good choice to find is the x-intercept, if only because you are often asked to find it.
Set y = 0 and solve for x.
0 = 2x + 3
-2x = 3
x = 3/-2 = -3/2
