A line passes through the point , 9−2 and has a slope of 43. Write an equation in point-slope form for this line.

y=43x-389

Step-by-step explanation:

use the y=mx+b formula

plug in 9 for "x" and 43 for "m"

then plug in -2 for y

-2=43(9)+b, multiply 43 and 9

-2=387+b

subtract both sides by 387

-389=b

hope this make sense( i dont think it does)

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
