Find the variation constant and an equation of variation where Y varies directly as X and Y=60 when X=10

k=variation constant
y=equation of variation

  • Algebra genius? - ,

    y=mx+b or y=kx+b (m is the standard symbol, which came to us 300 years ago from the French Academy, headed by Rene Descartes. It has served us well as the symbol for slope).

    y=mx+b
    60=m*10+b

    No since you state y varies directly as x, this implies b=0
    m=6

    Yikes, so K=0 and y=6? Help please..
