What is the y-intercept of a line that has a slope of -3 and passes through point(0, -7)? -7
-3
0
4

-7

Step-by-step explanation:

use y-y1 = m(x-x1)

y+7= -3(x-0)

y = -3x -7

use y=mx+b

b= -7

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.
