Question

given the values of x and y, find an equation of variation in which y varies directly as x.

y=400, when x=110

Answer 1

y = k x where k is constant
400 = k 110
k = 40/11
so, y = 40/11 x
11y=40x

Answer 2

i have x=3.64y
y=3.64x
y=0.28x
x=290y

Answer 3

\[\frac{40}{11}\approx3.64\]

Answer 4

across...is right

Answer 5

so y=3.64x?

Answer 6

yup

Answer 7

hey across

Answer 8

on the slope question tht answer seems too easy?
