The slope-intercept form:
y = mx + b
m - slope
b - y-intercept
We have the line y = 3x - 4.
The parallel lines have the same slope. Therefore we have y = 3x + b.
Put the coordinates of the point (3, 2) to the equation:
2 = 3(3) + b
2 = 9 + b subtract 9 from both sides
-7 = b → b = -7
Answer: y = 3x - 7
