Answer this in 2 steps:
1) Solve 3x+y=4 for y: 3x+y=4 becomes 3x-3x+y=4-3x, or y = -3x + 4.
1
2) Find the reciprocal of this result: 1/y = --------------
-3x + 4
Answer:
y=x+5
Step-by-step explanation:
Lines are parallel if they have the same slope, the Y-intercept does not matter. Since these line passes through point (0,5) it's y-intercept has to be 5 and It's still parallel with line y=x-7.
