Answer:

y = 2x - 3

Explanation:

Since the line needs to be parallel, you can take the slope of the other equation and input it into y = mx + b:

y = 2x + b

Next, to have it intercept at the given coordinates, input the coordinates into the equation and solve for b:

-1 = 2 ( 1 ) + b

-1 = 2 + b

-1 - 2 = b

-3 = b

Now input the "b" value into the equation and you have the answer:

y = 2x - 3
