How do you find the slope of the secant line PQ?
After plugging in the x values to find the different point Qs, you will take (y2-y1)/(x2-x1) for each pair of points to find the slopes of the secant lines. Then estimate the slope of the tangent line, which will be between the slopes for x=8.99 and x=9.01.

What is a secant line of a circle?
Secant Lines. A secant line is a line that intersects a circle at two points. Every secant line, therefore, contains a chord of the circle it intersects.
What is a secant of a circle?
In geometry, a secant of a curve is a line that intersects the curve in at least two (distinct) points. In the case of a circle, a secant will intersect the circle in exactly two points and a chord is the line segment determined by these two points, that is the interval on a secant whose endpoints are these points.
