If #y=166# when #x=83#, what is #y# when #x=23#? Algebra Graphs of Linear Equations and Functions Direct Variation 1 Answer Paramecium · Stefan V. May 19, 2017 #y# is #46#. Explanation: Use proportions: #(y_1 / x_1) = (y_2 / x_2)# #(166 / 83) = (y_2 / 23)# Multiply by #23# on both sides: #(166 / 83) * 23 = y_2# #46 = y_2# Answer link Related questions What is Direct Variation?
