Consider the circle (x-4)^2 + (y-1)^2 =9. There are two lines tangent to this circle having a slope of 0. (Hint: graph the circle to see)
a. Find the coordinates of the points of tangency.
b. Find the equations of the two tangent lines.

part a. (4, 4)   (4, -2)

part b. y = 4    y = -2

Step-by-step explanation:

Graph the 4 and 1 from (x-4)^2 + (y-1)^2 = 9

Hint: Graph the circle on Desmos

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
