It is very difficult to explain on a computer or without actually being face to face. It would be best if you could ask your parents or your teacher since I bet they could give you a better answer than anyone on here.

Y = – 1.3(x + 3)2 – 9
Naddika [18.5K]

Given equation, y = – 1.3(x + 3)2 – 9 is in slope intercept form.

Step-by-step explanation:

Slope intercept form standard formula:

                          y = mx + c

where,

         y= y intercept

         x= x intercept

        m = slope

        c = constant

We are given:

                          y = - 1.3(x + 3)2 - 9

                          y = - 2.6x + 7.8 - 9

                          y = -2.6x -1.2

So,

                 Slope = m = -2.6

                  constant = 1.2
