Explanation:
No, this isn't the correct answer.  
You have found the right gradient, but your \(y\)-intercept is not correct.
Just to recap, in gradient form  \(y=mx+c\),  \(c\) tells us the \(y\)-intercept.  Also remember the line passes through the point \(\left(0,1\right)\). To find \(c\) you'll need to sub the coordinate into the equation then rearrange.
