To solve by graphing, start by putting each equation into slope-intercept form, y = mx + b.

x - 3y = 3

x = 3y + 3

x - 3 = 3y

x/3 - 1 = y The intercept is -1. Put a point at (0, -1). The slope is 1/3. Go up one and right 3. Put a point. Draw line.

2x + 3x + 3y = -3

5x + 3y = -3

3y = -5x - 3

y = -5x/3 - 1 The intercepts is also -1. The slope is -5/3. Go down 5 and right 3. Put a point. Draw line.
