A = π r^2 = π[3/4 cm]^2 = 9π/16 cm^2

What is the slope of the line through (-3, 3) and (-1, -1)?
Vladimir79 [104]

Answer:

The slope is -2

Step-by-step explanation:

To find the slope, we can use the slope formula

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

    = (-1 -3)/(-1 - -3)

   = ( -1-3)/(-1+3)

   = -4/2

   = -2

The slope is -2
