The easiest way to do this is to use the slope intercept form of a line.
y = mx + b ; where m is the slope and b is the y intercept
You are given
2x=y
or
y+=+2x
so in this case, m = 2. Thus the slope is 2

Only use m+=+%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29 if you're given two points on the line. Here, you could find two arbitrary points and find their slope, but instead just write it in y = mx + b form --> y = 2x. Therefore the slope is 2.
