What is the slope of the line that passes through the points (2, 9)(2,9) and (18, -3)(18,−3)?

Respuesta :

The slope's formula is -->  [tex]\frac{y2-y1}{x2-x1}[/tex]

Let's set:

  • (x1, y1) = (2,9)
  • (x2, y2) = (18,-3)

   either other works, I just chose it that way

So:

  [tex]slope = \frac{-3-9}{18-2} =\frac{-12}{16} =-\frac{3*4}{4*4} =-\frac{3}{4}[/tex]

Hope that helps!
