Answer:

y = 3x + 2

Explanation:

First you need to change the way the equation is said into a easier form:

y = 3x - 5

Since the line is parallel, you can use the same slope of 3:

y = 3x + b

Now you plug in the coordinates into the equation and solve for b:

-7 = 3 ( -3) + b

-7 = - 9 + b

-7 + 9 = b

2 = b

Now plig this into the equation and you have the answer

y = 3x + 2
