slopes and I kinda have no clue how to do it

The equation of the line is given as:
[tex]y=\frac{1}{2}x-2[/tex]This is in the slope-intercept form.
Which is:
[tex]y=mx+b[/tex]Where
m is slope
b is y-intercept
Comparing the form to our equation, we can see that:
Slope = 1/2
y-intercept = -2
The graph of the line is shown below:
