Answer:
the value of k is
k = 1/2
Step-by-step explanation:
from the question y = kx,
where y = 12 and x = 24
we will first of all make k the subject of the formula
y = kx
divide both sides by the coeficient of k which is x
y/x = kx/x
y/x = k .................................. k is the constatnt of proportionality
since we are given the value of x and y , we slot it in to determine the value of k.
k = y/x
k = 12/24
k = 1/2
check if your answer is correct , put the value of k into te question and see if LHS = RHS
y = kx
12 = 1/2 × 24
12 = 24/2
12 = 12....................... PROVED
