Problema Solution
Assume that y is directly proportional to x. Use the given x-value and y-value to find a linear model that relates y and x.
x = 5, y = 1010
Answer provided by our tutors
y is directly proportional to x if there is a non-zero constant k such that
y = kx
for x = 5, y = 1010 we have:
1010 = 5k
5k = 1010 divide both sides by 5
k = 1010/5
k = 202
the linear model that relates y and x is:
y = 202x.
