Which equation represents the line through the points (3,2) and (-9,6) ? x + 3y = 9
3x - y = -9
O x - 3y =9
3x + y =9

Step-by-step explanation:

(3,2),(-9,6)

slope = (6 - 2) / (-9 - 3) = -4/12 = -1/3

y = mx + b

slope(m) = -1/3

use either of ur points...(3,2)x = 3 and y = 2

now we sub into the formula and find b, the y int

2 = -1/3(3) + b

2 = -1 + b

2 + 1 = b

3 = b

so ur equation is : y = -1/3x + 3 <==

step-by-step explanation:

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

hence, option a is correct.
