select the exact answer in terms of π and the approximate answer rounded to the nearest whole number.

(select all that is the answer.)

a. 320 m³

b. 102 π m³

c. 2149 m³

d. 684 π m³

e. 1922 m³

f. 612 π m³

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
