If y=166 when x=83, what is y when x=23? Algebra Graphs of Linear Equations and Functions Direct Variation 1 Answer Paramecium ยท 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?
