Question 130569
Find the slope of the line: y-5=0. 
<pre><font size = 4><b>
Get in the form  y = mx + b, then the slope will be m

y - 5 = 0
    y = 5

Insert the term 0x

    y = 0x + 5

Compare to

    y = mx + b

The slope m = 0, and the y-intercept is (0,b) or (0,5)

So the graph is this horizontal line:

{{{graph(300,300,-3,7,-3,7,5)}}}
