Answer:

Step-by-step explanation:
The slope-intercept form of an equation is determined by the constant equation
where
is the slope and
is the y-intercept of the line.
Therefore, we can use the equation given and implement it to find your slope.

Our equation does not have a y-intercept,
. Therefore, it can just be inferred as
.
Because we do have a
, we can then find out what our slope is:
.
