10 points. do not guess. guesses will be reported. you. : )

a. The radius is the distance from the circle's center to the point of tangency:

b. The line tangent to the circle is perpendicular to the line connecting points A and B. Lines perpendicular to one another have slopes that are negative reciprocals of one another. In other words, if the slope of the line through A and B is , then the slope of the tangent line is .

Find the slope of the line through A and B:

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
