Find the slope of the line through the points (-13,15), (20,-7)
kifflom [539]

Answer:

\boxed{ \bold{  \huge{\boxed{ \sf{ \frac{ - 2}{3} }}}}}

Step-by-step explanation:

Let the points be A and B

A ( -13 , 15 ) ⇒( x₁ , y₁ )

B ( 20 , -7 )⇒( x₂ , y₂ )

<u>Finding</u><u> </u><u>the</u><u> </u><u>slope</u><u> </u> :

\boxed{ \sf{slope =  \frac{y2 - y1}{x2 - x1} }}

plug the values

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

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

⇒\sf{slope =  \frac{ - 7 - 15}{20 + 13}}

Calculate the sum

⇒\sf{slope =  \frac{ - 22}{33} }

Reduce the numbers with G.C.F 11

⇒\sf{slope =  \frac{ - 2}{3} }

Hope I helped !

Best regards!!
