(4,3) and (1, 03) when I plot these two on a graph they are parellel. Am I correct. How do I find the slope of the line m=___?

Slope (m)= (y2y1)/(x2x1)
= (33)/(4+1)
m = 0
Using the point slope formula,
yy1 = m (xx1)
y3 = 0 (x4)
y3= 0
Therefore, y =3 is the equation which is parallel to the xaxis!!
Hope that helps :) 
for the numberator portion of your answer, subtract the 1st y value from the 2nd y value (remember your ORDER as the same order will apply to the x values later).
next, do the same for your x values.
this is what it looks like:
3 03 0
 +  = "0"
4 (1) 5
your slope is zero which means you have a horizontal line
