Remark
The slope intercept form is
y = mx + b
Note that the y has 1 as its coefficient and b is related to the 11 (which is neither an x or y term)
Solution
Subtract 2x from both sides.
2x - 2x - 5y = 11 - 2x Combine like terms
-5y = 11 - 2x Divide by - 5
-5y/-5 = 11/-5 - 2x/-5 Do the division
y = -11/5 + 2x / 5 Answer
Discussion
This is not the only answer
It could be
y = 0.4x - 2.2
