Question

Find the variation constant and an equation of variation where y varies directly as x and y=48 when x=8. The variation constant k=?
The equation of variation is y=?

Answer 1

PLEASE EXPLAIN!!

Answer 2

direct variation means y=kx y varies directly with x. k is a multiplier.
they tell you y=48 when x=8, so plug these numbers into the equation:
48=k*8
solve for k
the equation is y= kx with k replaced with the value you just found.
