Can someone help me like ASAP ! For the first six exercises, find the slope of the line AB. For the remaining exercises, find the
slope of the line that passes through the two given points. Cross out each box in the rectangle
below that contains a correct answer. When you finish, print the letters from the remaining
boxes in the spaces at the bottom of the page.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
