Which equation represents the line that passes through the points (4, 6) and (-2, -1)?
1 answer:
Answer:
y = 7/6x + 4/3
Step-by-step explanation:
find slope first
change in y over the change in x
-1-6/-2-4 = -7/-6 = 7/6
to be extra sure use this formula to find the y-intercept or b
y - 6 = 7/6 (x -4)
you can plug in either point
solve for y and you have the equation in slope intercept form or y=mx+b

volume = PI x r^2 x H
you know the volume and the radius ( 12/2 = 6)
480.66 =3.14 x 6^2 x H
480.66 = 113.04 x h
h = 480.66/113.04 = 4.252
round off as needed.
