Answer:

y=3x-7

Explanation:

we use the equation of the line:

y=mx+b

if the line is parallel, then the slope(m) of the line stays the same:

y=3x+b

we then substitute the ordered pair into the equation and solve for b:

-13 = 3(-2)+b

-13 = -6+b

-13+6 = b

-7 = b

now we substitute the b value into the original equation and the answer:

y=3x-7

Hope this helps :)
