Answer:
the first answer ( I think these are 3 different questions) is y = -4x + 7
the second answer is y = -3x + 5
the third answer is y = 6x - 5, because the lines are parallel, they have the same slope and the y int is -5 from the point given.
Answer:
See below
Step-by-step explanation:
- 6x² - 18 =
- 6*x² - 6*3 =
