Question: There are exactly two lines that pass through(1,3)(1,3)that are also tangent to the parabolay=x2y=x2. Determine the equations of these lines and their points of tangency

There are exactly two lines that pass through(1,3)(1,3)that are also tangent to the parabolay=x2y=x2. Determine the equations of these lines and their points of tangency with y=x2y=x2.Explain this question using the simplest grade 9 math method. Like b^2-4ac or something else. But I am in grade 9 and I don't know about derivatives so do not use them.
