Answer; A: Right scalene. Square on the corner tells you it's a right triangle. It's a scalene triangle because none of the sides are equal.
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:
