Answer:
Explanation:
First Rewrite Equations Where it Applies
You would plug in sample values for x and see the output for y
Graph those sample values
See where the graphs intersect each other
That is the answer
1.
a)y=x+3
b)y=-2x-3
| x | y (a) | y (b) |
| --- | ----- | ----- |
| -2 | 1 | 1 |
| -1 | 2 | -1 |
| 0 | 3 | -3 |
| 1 | 4 | -5 |
| 2 | 5 | -7 |
2.
a)y=2x+6
b)y=2x+2+4 distribute so y=2x+6
| x | y (a) | y (b) |
| --- | ----- | ----- |
| -2 | 2 | 2 |
| -1 | 4 | 4 |
| 0 | 6 | 6 |
| 1 | 8 | 8 |
| 2 | 10 | 10 |
I will use an online graphic calculator - I attached some photos
1) (-2,1)
2) y=2x+6 why? It's the same equation so it is the same line
