## Answers ( )

Note: this answer assumes that the equation of the line must be in slope-intercept form.Answer:Explanation:When you need to write an equation and know its slope and a point it intersects, you can use the point slope formula first. In order to write an equation using this formula, the , , and must be substituted in for real values.

The represents the slope, so write the slope of this equation, -3, in its place. The and represent the x and y values of a point the line intersects. We know that the line must intersect the point (2, -1). Write 2 in the place of

Now, to put it in slope-intercept or form, just expand the right side and isolate :

Therefore, is the answer.
