The line is parallel to
tino4ka555 [31]

Recall that parallel lines have the same slope.

A line parallel to y= (-3/5)x + 8 would have the same equation EXCEPT for a different constant, C, replacing that '8.'

This new line passes thru (-5,-3).  In y= (-3/5)x + C, replace x with -5 and replace y with -3.  Then:

-3 = (-3/5)(-5) + C.  Find C:

-3 = 3 + C.  Thus, C = 6


Thus, the equation of the new line is y= -(3/5)x - 6

Check:  Let x = -5 and y = -3.  Is the above equation true?

-3 = (-3/5)(-5) - 6

-3 = 3 - 6, or -3 = -3.

Suppose that you want to design a cylinder with the same volume as a given cylinder but you want to use a diff radius and height
Anton [14]

Answer:

Yes, r and h can be changed to produce same volume by;

Increasing "r" and decreasing "h" or by decreasing "r" and increasing "h".

Step-by-step explanation:

What the question is simply asking is if we can get same volume of a particular cylinder if we change the radius and height.

Now, volume of a cylinder is;

V = πr²h

Now, for the volume to remain the same, if we increase "r", it means we have to decrease "h", likewise, if we decrease "r", we now have to increase "h".
