How to find the equation of a line in slope intercept form that passes through one point and is perpendicular to an equation?

When two lines are perpendicular, their slopes are negative reciprocals.

Suppose you were given the function f(x) = x4 − 2x3 + 3x2 − 10x + 3 and the factor (x − 2). what is the value of a?     to save confusion, use " ^ " to denote exponentiation:           f(x) = x^4 − 2x^3 + 3x^2 − 10x + 3 and the factor (x − 2). what is the value of a?   you have not explained what "a" represents.  could you do that, ?   then we could probably find its value.
