Answer:
[tex] \huge{ \bold{ \boxed{ \tt{( - 1 \: , - 4)}}}}[/tex]
Step-by-step explanation:
Let the point R ( - 3 , - 7 ) be ( x1 , y1 ) and S ( 1 , -1 ) be ( x2 , y2 ).
[tex] \text{Finding \: the \: midpoint} : [/tex]
[tex] \boxed{ \sf{midpoint = ( \frac{x1 + x2}{2 } \: , \frac{y1 + y2}{2} )}}[/tex]
[tex] \sf{➳midpoint = ( \frac{ - 3 + 1}{2} \:, \frac{ - 7 + ( - 1)}{2} })[/tex]
[tex] \text{Remember} : [/tex]
- ( + ) * ( - ) = ( - )
- ( - ) * ( + ) = ( - )
- ( + ) * ( + ) = ( + )
- ( - ) * ( - ) = ( + )
[tex] \sf{➳midpoint = ( \frac{ - 3 + 1}{2} \: , \frac{ - 7 - 1}{2} )}[/tex]
[tex] \text{Remember} : [/tex]
- The positive integers are always added and posses the positive ( + ) sign.
- The negative numbers are always added but posses the negative sign ( - ).
- The negative and positive integers are always subtracted but posses the sign of the bigger integer.
[tex] \sf{➳midpoint = ( \frac{ - 2}{2} \: , \frac{ - 8}{2} )}[/tex]
[tex] \sf{➳midpoint = ( - 1 \:, - 4})[/tex]
