 Equation must be solved for y=
 Given: 2x – 3y = 12
 -3y = -2x +12
 y = 2/3 x -4
 Y = m x + b
 Where m = slope = rise
 run
 The y-intercept is b.
 Y=2/3x -4
1) Plot the y intercept: (0, -4)
2) Starting fromTHAT intercept , rise 2 and
then go right 3. Plot this new point.
3) Repeat step 2.
4) Using a ruler, draw a line, with arrows at each
end!
