tangent equations parrallel or perpendicular to ...

ok i have two question's i can't answer;

#1) find the equations of the tangents to the curve $\displaystyle y = x^3 -3x^2 -7x +5$ that are parrallel to the line with equation $\displaystyle y = 2x - 3$

i realise that it being parrallel the gradient would be the same. i also know you can solve these algabraicly just lacking the know how :)

#2) find the equation of the tangent line to the curve with equation $\displaystyle y = e^2x-6$ that is perpendicular to the line with equation $\displaystyle y = 5 - \frac {x}{2}$

same sort of deal, i realise it being perpendicular it has the gradient of a normal. don't know how to figure these out algabraicly.

thankin you kind people of math help forum.
