Answer:
options b ... on the y axis only the x coordinate is always 0
1/6 + 1/3 + 1/2 is 1
first u need to find the GCF which is 6 here
convert all the denominators to 6
1/6 + 2/6 + 3/6
when you add them all together u get 6/6 which is also equivalent to 1
Discriminant b^2-4ac = (-9)^2 - 4*2*9 = 9
so there are 2 roots
because of the -9x and 9 they will both be positive
You use variables for the equation and after you find out the variables you set them equal to each other and see if they are equal
