Write a program using tensorflow to calculate : $$y=mx+c$$

Part 1

1. Read 2 arrays x,y containing floating point values
2. Calculate mean of x & y
3. Calculate variance for x $$variance(x)=sum((x-mean(x))^2)$$
4. Calculate covariance of x & y $$covariance = sum((x(i) - mean(x)) * (y(i) - mean(y)))$$
5. Calculate value of m $$m = covariance(x,y)/variance(x)$$
6. Calculate value of c $$c = mean(y) -m* mean(x)$$

Part 2

1. Plot graph for actual values against predicted value
2. Calculate root mean square error.
