x-3y=3, 2x+3x+3y=-3 solve by graphing

Question

How to solve this dont know were to start

Answer 1

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.
