Using quadratic function concepts, it is found that Abby made a mistake on the coordinates of the vertex, which are (-4,1).
----------------------
- A quadratic function is defined by:

- The y-intercept is given by point:

- The vertex is given by:
. - The axis of symmetry is:

----------------------
The function given is:

- Which is a quadratic equation with:
.
, thus, the y-intercept is (0, -15).

- Thus, the <u>x-coordinate of the vertex</u> is x = -4, which is the same as the <u>axis of symmetry</u>.

- The vertex is given by: (-4,1).

Make sure it has eight sides
Answer:
A: 9x-3y =5
Step-by-step explanation:
slope of the line = (8-(-1))/(-1)-(-4) = 3
so y = mx+ c , where m= slope
the equation 9x-3y= 5 has the slope 3 since we can make y the subject of the formula to get
y= 3x - 5/3..here m is also equal to 3
