You plot the coordinates then use the slope of 3 as 31

Explanation:

To plot the point, move 2 to the right on the x-axis then 1 down (y-axis). Then look at the slope. 3 is also equal to 31 (3 over 1) as a fraction.

In a fraction there are two parts, the numerator (top number in this case 3) and the denominator (bottom number in this case 1).

The numerator shows the rise (number of spaces you go along the y-axis) and the denominator shows the run (number of spaces you go along the x-axis).

So from the point (2,โˆ’1), you go up (since it is a positive slope) 3 spaces and to the right 1 space.
