Answer:

Step-by-step explanation:

Slope = (change in y)/ (change in x)

          = (13 - 3)/(1 - (-1))

           = (13 - 3)/(1 + 1)

           = 10/2

           = 5

What is K+(-5/3)=-44/3​
Natalija [7]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf k =  - 13}}}}

Step-by-step explanation:

\sf{k + ( -  \frac{5}{3} ) =  -  \frac{44}{3} }

When there is a ( + ) in front of an expression in Parentheses, there is no need to change the sign.

That means the expression remains the same.

⇒\sf{k -  \frac{5}{3}  =  -  \frac{44}{3} }

Move 5/3 to right hand side and change it's sign

⇒\sf{k =  -  \frac{44}{3}  +  \frac{5}{3} }

While performing the addition or subtraction of like fractions , you just have to add or subtract the numerator respectively in which the denominator is retained same.

⇒\sf{k =  \frac{ - 44 + 5}{3} }

Calculate

⇒\sf{k =  \frac{ - 39}{3} }

Divide -39 by 3

⇒\sf{k =  - 13}

Hope I helped!

Best regards!!
