Question 196479
The equation you are given is in slope intercept form. {{{y = mx + b}}}
Where b is the y intecept (so one point on the line is (0,3) and the slope is -2

Slope is rise/run, So go down 2 units and to the right 1. Then plot another point. Keep doing that as many times as you wish. All the points will fall on the same line.
