What is the equation of the circle with centre (0, 0) and radius 8 units?
y = 8x
x2 + y2 = 8
x2 + y2 = 64
Find the equation of the tangent to the circle x2 + y2 = 10 at the point (1, 3).
y = 3x + 10
y = \(\frac{1}{3}x + \frac{8}{3}\)
y = \(-\frac{1}{3}x + \frac{10}{3}\)

(2, -5)
(2, 5)
(-2, -5)
A quadratic graph passes through the points (2, 0) and (-3, 0). A possible equation for this graph is:
y = (x + 2)(x – 3)
y = (x + 2)(x + 3)
y = (x – 2)(x + 3)
