Question 19090
These equations are both in what is called slope-intercept form.  The formula for slope intercept form is {{{y=mx+b}}}
In this formula, x and y are coordinates that vary depending on the point on the graph.  m is the slope and will remain constant for any point on the graph.  b is the y-intercept and is the equivalent of the coordinant (0,b), ei. it says, "when x is zero, y is b."
Therefore, in the first equation, the slope is 1/2
