Question 119965
Write a direct variation equation that has (3,11) as a solution. Then find y when x=12.
:
y = k*x
or
kx = y
:
Substitute 3 for x and 11 for y and find k
3k = 11
k = {{{11/3}}}
;
Now we have: y = {{{11/3}}}x, as our equation
:
Find y when x = 12
 y = {{{11/3}}}*12
 y = 11*4; cancel out the denominator
 y = 44, when x = 12

How about this? Did I make it understandable to you?
