Step-by-step explanation:
that should be right
Answer:
p = 
Step-by-step explanation:
Given that p varies inversely with q then the equation relating them is
p =
← k is the constant of variation
To find k use the condition p = 2 when q = 1, thus
k = pq = 2 × 1 = 2
p =
← equation of variation
Table:
x 0,1
y -2,0

Answer:
A point that must lie on this line is the origin (0,0)
Step-by-step explanation:
we know that
The equation of the line in standard form is equal to

where
A is a positive integer
B and C are integer
In this problem
C=0
so

That means, that the line represent a proportional relationship between the variables x and y
Remember that in a proportional relationship the line passes through the origin
therefore
A point that must lie on this line is the origin (0,0)
