What is the slope of the line passing through the points (-5,9) and (2,-12)

-3

Step-by-step explanation:

To find the slope of a line given two points, we use:

.

Or you could line up the points vertically and subtract the points vertically, then put 2nd difference over 1st difference.

That looks like this:

(  2  ,  -12)

-( -5  ,  9   )

----------------

  7         -21

So the slope is -21/7 which gives you -3.

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
