You can put this solution on YOUR website!
Function is given in implicit form, so we solve for y:
x-2y=1 /-x
-2y=1-x /*(-1)
2y=x-1 /:2
y = (x-1)/2
We can determine slope by evaluating derivative: y'= (x-1)*1/2 y'=1*1/2 slope equals to one half.
Next we detrmine y intercept by setting x= 0
y= 0-1/2
y = -1/2
