Answer:
3x + y = -12.
Step-by-step explanation:
y + 3 = 3(x+5)
y + 3 = 3x + 15
3x + 15 = y + 3
3x - y + 15 = 3
3x + y = -12
Answer:
3x - y = - 12
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
given
y + 3 = 3(x + 5) ← distribute
y + 3 = 3x + 15 ( subtract y from both sides )
3 = 3x - y + 15 ( subtract 15 from both sides )
- 12 = 3x - y, thus
3x - y = - 12 ← in standard form
