hello!
===========================================================
This equation is written in slope-intercept form, which looks like so:-
where
m is the slope
b is the y-intercept
Now, what is the slope?
Hint:- The slope is the coefficient of x, and the y-intercept is the constant.
That's right! The slope is 3, and the y-intercept is -4.
