Answer:


\boxed{ \bold{ \huge{\boxed{ \sf{ ( - 2)/(3) }}}}}

Explanation:

Let the points be A and B

A ( -13 , 15 ) ⇒( x₁ , y₁ )

B ( 20 , -7 )⇒( x₂ , y₂ )

Finding the slope :


\boxed{ \sf{slope = (y2 - y1)/(x2 - x1) }}

plug the values


\sf{slope = ( - 7 - 15)/(20 - ( - 13)) }

We know that,
\sf{( - ) * ( - ) = ( + )}


\sf{slope = ( - 7 - 15)/(20 + 13)}

Calculate the sum


\sf{slope = ( - 22)/(33) }

Reduce the numbers with G.C.F 11


\sf{slope = ( - 2)/(3) }

Hope I helped !

Best regards!!
