Graphing Systems
3x - 4y = 16
x + y = 3
What is (4, - 1)?
What is the solution (x,y) to:
4x - y = - 19
- 4x - 10y = - 14
What is (-4,3)?
Name the transformation:
y = | x - 1 |
What is shifted one unit right?
Solve:
| - 1 + x | - 4 = 4
What is {9, - 7}?
What is the solution to the system (by graphing):
3x - y = - 4
2x - y = - 1
What is the solution to the system:
-3x + 6y = - 24
-9x - 6y = - 24
What is (4, -2)?
Identify the vertex of the graph:
y = |x - 2| - 4
What is (2, 4)?
Solve:
| - 8x | + 1 = 81
