1. Where do these graphs intersect

2. Are These Parallel? 1. y = x + 3 y = 3x - 12 3. y – x = 1 y = -x - 1

3. Lets try one: Find the solution to the following system:
y = -2x+4
y = x -2
m= b=4
m=1 b=-2
Step 1:Graph both equations
Step 2: Find
Where the lines intersect?
THE SOLUTION: (2,0)

4. You try: Where do the lines intersect?
y = 2x – 1
y = –x + 5
Graph both equations
Where do they intersect?

5. Try again: Find the solution to the system
y = -2x-1
y = -2x+4
Graph both equations
Where do they intersect?

6. Find the Solution
