Transform each linear function into the form y=mx+b. Show the process of your answer.
1. x + y = 2
Solution:
[tex]x + y = 2 \\ \\ x + y + ( - x) = 2 + ( - x) \\ \\ y = -x + 2[/tex]
Answer:
[tex]y = - x + 2[/tex]
2. 2x - y = 5
Solution:
[tex]2x - y = 5 \\ \\ 2x - y + ( - 2x) = 5 + ( - 2x) \\ \\ - y = - 2x + 5 \\ \\ \frac{ - y = - 2x + 5}{ - 1} \\ \\ y = 2x - 5[/tex]
Answer:
[tex]y = 2x - 5[/tex]
3. -9x-3y = 12
Solution:
[tex] - 9x - 3y = 12 \\ \\ - 9x - 3y + 9x = 12 + 9x \\ \\ - 3y = 9x + 12 \\ \\ \frac{ - 3y = 9x + 12}{ - 3} \\ \\ y = - 3x - 4[/tex]
Answer:
[tex]y = - 3x - 4[/tex]
