A=pir²
64=pir²
divide both sides by pi
64/pi=r²

Find the slope in (-2,8) and (1,6)

Salsk061 [2.6K]

Formula for slope: $\frac{y2 - y1}{x2 - x1}$

y₂: 6

y₁: 8

x₂: 1

x₁: -2

Plug them into the slope equation:

$\frac{6 - 8}{1 - (-2)}$

--> $\frac{-2}{1 + 2}$

---> $-\frac{2}{3}$

The slope is $-\frac{2}{3}$ .
