Answer:
y = 36x
Step-by-step explanation:
Given that y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 18 when x =
, thus
k =
=
= 36
y = 36x ← equation of variation
Answer:
D
Step-by-step explanation:
Answer:
y-axis is x = 0
Step-by-step explanation:
if P(x, y) is any point on AB, then x = a. Hence, the equation of a straight line parallel to the y-axis at a distance from it is x = a. The equation of the y-axis is x = 0, since, the y-axis is parallel to itself at a distance 0 from it.
