Answer:
a. y=-2x
Step-by-step explanation:
The equation of a direct proportion is of the form where k is the constant of proportionality.
From the given options, the only equation that is of the form, is
.
In this case is the constant of proportionality.
Therefore the correct option is A.
it would be on y-4.
and there is no x coordinate because it's 0
m = 12.9g
v = 8cm3
d = ?
d = m/v
d = 12.9g/8cm3
D = 1.6125g/cm3
490/30 = 82
you simply just divide the two numbers to get slope
