find the y-intercept for each of the new equations:

A) write an equation of the line that passes through (1,7) and is parallel to the line:
[tex]y = 3x + 2[/tex]


B) write an equation of the line that passes through (9,2) and is parallel to the line:
[tex]y = \frac{5}{3} x + 9[/tex]

C) write an equation of the line that passes through (-1, 8) and is parallel to the line:
[tex]y = 6[/tex]

please answer ASAP. also include explanation, this is on my class work, and I have no idea how to solve it
