(a) Find the slope of the line through (-9, -7) and (-19. -47).

4

Step-by-step explanation:

The equation for slope is:

We can plug in the given points into the equation:

The slope is 4

( x+2)^2 + (y+5)^2 = 1

Step-by-step explanation:

The equation of a circle can be written in the form

( x-h)^2 + (y-k)^2 = r^2

where ( h,k) is the center and r is the radius

( x- -2)^2 + (y- -5)^2 = 1^2

( x+2)^2 + (y+5)^2 = 1
