Aline has a slope of 1/4 and passes through point (0.4,-1/2). what is the value of the y-intercept?

Find the zero function by factoring (try to show work) h(x)=-x^2-6x-9

It is given that the quadratic equation hx²-3x+k=0, where h and k are constants, has roots [tex] \beta \: and \: 2 \beta [/tex]express h in terms of k
