The equation is written in slope-intercept form (y=mx+b), where m is the slope and b is the y-intercept).
Notice that the slope is the coefficient of x (the number before x)
So we already know the slope of the given line.
The slope is:-
[tex]\boxed{\frac{1}{2} }[/tex]
The y-intercept is:-
-4 (the y-intercept is a constant (a number with no variables next to it)
Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)
