Answer 1

Answer:

y = 3x + 7

Step-by-step explanation:

y = mx + c

Rearrange "3x - y +2 = 0"

-y = -3x -2

y = 3x + 2

m = 3

Substitute into general equation:

y = 3x + c

4 = 3(-1) + c

4 = -3 + c

7 = c

Therefore:

y = 3x + 7

Answer 2

Answer:

-y = 3x - 4

Step-by-step explanation:

1. - 3x to get - y + 2 = - 3x
2. - 2 to get - y = - 3x - 2
3. Replace the - 2 with 4 from the points
4. Make it a negative
