Solve each of the quadratic equations.
3x = 0.5x2

.5x^2 -3x = 0
take out a common factor of 'x'
x(.5x - 3) = 0
Set each factor equal to zero and solve.
x = 0
.5x - 3 = 0
add 3 to both sides
.5x = 3
divide both sides by .5
x = 6

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
