Answer:

  • your graph is correct
  • y = 3x -5

Step-by-step explanation:

The graph shows you the line has a "rise" of 1-(-2) = 3 for a "run" of 2-1 = 1, so the slope is 3/1 = 3.

The y-intercept is seen to be -5, so the equation is ...

  y = mx +b . . . . . where m is the slope (3) and b is the y-intercept (-5)

  y = 3x -5

__

The points and line are plotted correctly, so you already have your graph.
