Step-by-step explanation:
This equation is known as slope-intercept form.
Parts of the slope-intercept form equation:
[tex]y=mx+b[/tex]
m represents the slope.
b represents the y-intercept.
In the equation, [tex]-\frac{1}{2}[/tex] is in the placement of m.
We can conclude that [tex]-\frac{1}{2}[/tex] is our slope.
