Answer: Option d.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
In this case we know that the slope of the line is:
Knowing that it passes through the point (2, -1), we can substitute the coordinates into and solve for "b":
Therefore, the equation of this line in Slope-Intercept form is:
Written in Standard form, this is:
