How do you find the value of y for a given value of x if y is 3.3 when x is 1.65, what is y when x is 4.85? Algebra Graphs of Linear Equations and Functions Direct Variation 1 Answer Jumbotron Aug 19, 2017 #y=9.7# Explanation: #y~x# #y=xk# where #k# is constant.. #k=y/x# When #x=1.65, y=3.3# #k=3.3/1.65# #k=2# #y=2x# When #x=4.85# #y= 2 xx 4.85# #y=9.7# Answer link Related questions What is Direct Variation?
