Answer:
4x + y - 6 = 0
Step-by-step explanation:
Recall that parallel lines have the same slope. Thus, the equation of the new line has the form 4x + y - C = 0, the same as 4x + y + 1 = 0. We need only find C.
To do this, substitute 1 for x and 2 for y: 4(1) + (2) + C = 0, or
4 + 2 = -C, so that C = -6
Then the desired equation is 4x + y - 6 = 0
