test on Monday.
12/11 Review
12/11 Review
y=x+6
y = -x + 4
y = -1/3x + 5
y = 4/3x
12/11 Review
4x + 3y = 8
x - 2y = 13
10x + 16y = 140
5x – 8y = 60
12/11 Review
Changing Ax + By = C into y= mx + b
6x + 4y = 8
x + 5y = 5
1. Move “Ax” to other side.
• Remember: change sides,
change signs
2. “B” goes under and over.
Changing y= mx + b into Ax + By = C
y = 4/3x – 3
y = -3/2x + 2
Move “mx” to other side.
• Remember: change sides,
change signs
