Best ResponseYou've already chosen the best response.1x^2+2.2x+1.21 = 0 this can be factored, and 1 ,1.2 is incorrect

Best ResponseYou've already chosen the best response.1now for 2nd eq., put x=0 for yint., yx^2=7x y=0 so yintercept = (0,0) put y=0 for xint yx^2=7x 0=x^2+7x i believe u can solve this
