You may use a calculator for all of the questions in this quiz.
1) A circle has a centre at the origin and it passes through the point (-2, 4). What is the equation for the tangent to the circle at the point (-2, 4)? Give your answer in the form y = mx + c (the values for m and c may not be integers).
There is a sketch of the graph below to help you answer this question.

2) A circle has a centre at the origin and it passes through the point (4, 12).
a) Sketch the circle and label the point (4, 12). Also, draw a tangent to the circle at the point (4, 12).
b) Find the equation for the tangent to the circle at the point (4, 12)? Give your answer in the form y = mx + c (the values for m and c may not be integers).
3) A circle has a centre at the origin and it passes through the point (-3, -7).
a) Sketch the circle and label the point (-3, -7). Also, draw a tangent to the circle at the point (-3, -7).
