Manage the solution in either slope-intercept form or in point-slope form. Most people learn slope-intercept form first.

y=mx%2Bb
b=y-mx
b=1-2%28-1%29
b=3
-
highlight%28y=2x%2B3%29.

THE GRAPH:
Plot the point (0,3).
Find ANY point which is 2 units upward and 1 unit rightward;
Use a straight-edge to draw the LINE through both points.
