Given the following linear equation in Standard Form:

2x + 3y = 18

Solve for "y" by changing the problem to look like Slope - Intercept Form y = mx + b so that we can graph it in our calculators.

• $y\ =\ \frac{3}{2}x\ +\ 6$

• $y\ =\ \frac{2}{3}x\ -6$

• $y\ =\ \frac{-3}{2}x\ -6$

• $y\ =\ \frac{-2}{3}x\ +\ 6$
