Is there a graph for this problem?
Do the brackets first as it says in BIDMAS
Hmmm lemme do the first one only
For this case we must find the slope of the following equation:

By definition, the point-slope equation of a line is given by:

Where:
: It is a point through which the line passes
m: It's the slope
So, the slope of the given equation is:

Answer:
Option D
