The general equation for lines is:
y+=+mx+%2B+b
where m is the slope and b is the intercept.
In this case, we are told that m=2. So once we find b, we're done.
We know that the line passes through (-5, -17), so we simply plug these values into the equation and then solve for b:
y+=+2x+%2B+b
-17+=+2%2A%28-5%29+%2B+b
b+=+-7
The equation is then y = 2x - 7
