Answer:

Step-by-step explanation:
the quadratic function should be as follows:

Now let's confirm that the zeros of the function are 0 and 8

Therefore we can see that if x = 0

the equation is fulfilled
And we also have 
for this expresion to be equal to zero:

thus, if x = 8

the equation is also fulfilled
The zeros of the quadratic function
are 0 and 8.
The point-slope form is:

So, here, you just plug in values:

It would be + 1 because remember, the '-' sign just means the opposite of, not subtraction in this case. Also, m = slope.
