Question

(19.-2).(-11, 10) find the slope

Answer 1

Answer:

   $\large\boxed{\large\boxed{slope=-2/5}}$

Explanation:

The problem is: given the points (19,−2) and (−11,10) find the slope of the line that joins them.

The slope of a line is the change in the y-coordinate over the change of the x-coordinate:

• slope = rise / run = Δy / Δx

Thus:

         $slope=[10-(-2)]/[-11-19]\\\\slope=12/(-30)\\\\slope=-12/30$

Simplify, dividing both numerator and denominator by 6:

            $slope=-2/5\leftarrow answer$
