(PT)^2 = PA . PB
PA = 15 + x
x = Diameter

-> 31^2 = (15 + x) . 15
-> 961 = 225 + 15 x
-> 15x = 961 - 225
-> 15x = 736
-> x = 736/15
-> x = approximadately 49

Answer: 1st Option (49.1)

The diameter is about 49.1
You can find this using the equation: 31^2 = 15 x (15+diameter)

Hope this helped!!

Slope = 4/3, (-2, 11)

Lady_Fox [76]

Answer:

y = $\frac{4}{3}$ x + $\frac{41}{3}$

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = $\frac{4}{3}$ , hence

y = $\frac{4}{3}$ x + c ← is the partial equation

to find c substitute (- 2, 11) into the partial equation

11 = - $\frac{8}{3}$ + c ⇒ c = $\frac{41}{3}$

y = $\frac{4}{3}$ x + $\frac{41}{3}$ ← equation of line
