) What is the slope and y-intercept of this line? y = –4x + 7

Question 8 options:

slope: 4, y-intercept: –7

slope: –4, y-intercept: 7

slope: 7, y-intercept: –4

slope: -7, y-intercept: -4

slope: -4 y intercept 7

Step-by-step explanation:

when using the formula y=mx+b

The slope is the fraction for m -4/1 or -4.

The y intercept is 7 and thats where the graoh starts.

5y

step-by-step explanation:

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.

hope this !
