1-for what value of x is line a parallel to line b 2-for what value of x is line a parallel to line b

F(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 h(x) = x + 5 arrowright h(x) = x + 3 arrowright h(x) = x + 4 arrowright h(x) = x − 1 arrowright

Ab and bc form a right angle at point b. if a= (-3,-1) and b= (4,4) what is the equation of bc?
