Question

Please help!
What is the equation of the line passing through (–3, –9) and parallel to the line y = x + 6 in standard form?

x + y = –6

x + y = 6

x – y = –6

x – y = 6 <--- My guess

Answer 1

ur guess is correct

Answer 2

y = x + 6.. has slope = 1

so the parallel line through (-3,-9) must also have slope = 1
y = x + b

plug in the point and solve for b
-9 = -3 + b
b = -6

and the line is
y = x - 6

and in standard form...
x - y = 6
