Answer:

y = (1/4)x - 3

Step-by-step explanation:

The slope-intercept form is y = mx + b.  Here we are told that the line passes through (-8, -5) and that its slope is 1/4 (is that correct?).  

Substituting -5 for y, -8 for x and 1/4 for m, we get an equation for the y-intercept, b:

-5 = (1/4)(-8) + b, or

-5 = -2 + b, so b = -3, and the desired equation is

y = (1/4)x - 3

What is the volume of the cylinder below use formula v=ñr2 h
Vikki [24]

Answer:

The volume of the cylinder = π r² h

where r is the radius of the cylinder and h is the height of the cylinder.

This is formula is applied for the right cylinder as figure 1 and oblique cylinder as figure2.

<u>The volume of the cylinder of figure 1:</u>

r = 6  and  h = 7

volume = π r² h = π  * 6² * 7 = 252π   units³

<u>The volume of the cylinder of figure 2:</u>

r = 11  and  h = 15

volume = π r² h = π  * 11² * 15 = 1,815π   units³
