6 A curve has parametric equations
$$x = t ^ { 2 } - 6 t + 4 , \quad y = t - 3 .$$
Find
- the coordinates of the point where the curve meets the \(x\)-axis,
- the equation of the curve in cartesian form, giving your answer in a simple form without brackets,
- the equation of the tangent to the curve at the point where \(t = 2\), giving your answer in the form \(a x + b y + c = 0\), where \(a , b\) and \(c\) are integers.
