This is about circle theorems. someone asap : (

Find the equation of a line that is perpendicular to line g that contains (p, q). coordinate plane with line g that passes through the points negative 3 comma 6 and 0 comma 5 3x − y = 3p − q 3x + y = q − 3p x − y = p − q x + y = q − p

If f(x) and g(x) are inverse functions of each other, which of the following shows the graph of f(g(x)
