Differentiate to find out what is the gradient of the curve at any point along the curve. Then use that to find the gradient at x=0. After which, solve for the gradient of tangent and normal. And get the equation.

For part 2, know that intercept the x-axis means y coordinates are 0. So, kind of visualise a triangle formed, find the two xcoordinates, to get the base of triangle and solve accordingly !
