Choose the slope and y-intercept that
correspond with the graph.

slope = 2 and y- intercept = - 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m =

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (2, 2)

m = = = 2

The y- intercept is the value of the y- coordinate at the point where the line crosses the y- axis, that is

y- intercept = - 2

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.
