Suppose y varies directly with x and y=24 when x=8. What is the value of when x=10? Algebra Graphs of Linear Equations and Functions Direct Variation 1 Answer Binayaka C. ยท Geoff K. Jan 7, 2017 y=30 Explanation: y prop x or y =k*x or k=y/x ; , k is constant of variation. y=24 ;x =8 :. k=24/8=3 :. y= 3x So When x=10 ; y=3*10=30 y=30 [Ans] Answer link Related questions What is Direct Variation?
