HELP!!!!!!!!!!! Determine the equation of the graph, and select the correct answer below. ​
ss7ja [257]

The correct answer is

y =  - (x + 2)^{2}  - 4

There are three transformations to the parent function. The first is a negative sign on the left side. This makes the parabola open downward. Next, the +2 inside the parentheses moves the parabola left 2. Lastly, the -4 on the outside moves the parabola down 4.

What is the slope of the line that contains the points (-2, 7) and (2, 3)?
stealth61 [152]

Answer:

-1

Step-by-step explanation:

We can use the slope formula when given two points

m= ( y2-y1)/(x2-x1)

   = ( 3-7)/(2 - -2)

   = (3-7)/( 2+2)

   = -4/4

    = -1
