y = (15-6x)/7z
Answer:
The volume are equal
Step-by-step explanation:
Because when you multiply them both they are still equal.
Answer:
you want to isolat U on one side, so subtract 9/-4 from both sides to end up with (9/-4) - 9 = u, then solve. (9/-4)-9 = -11.25, so -11.25 = u
Slope is

if we plug in your coordinates we get:

Therefore, the slope of (0,1) and (2,7) is 3.
