4(-2 , 3) - 2(6 , -7)
(-8 , 12) + (-12 , 14)
Combining the x and y terms:

Answer 2

Explanation:

alright lets get started.

the linear combination is given by :

`4(-2,3)-2(6,-7)`

foiling 4 and 2 into the parenthesis

`(4*-2, 4*3)+(-2*6,-2*-7)`

`(-8, 12)+(-12,14)`

Combinig x and y terms together

`(-8-12, 12+14)`

`(-20,26)` : answer

Hope it will help. :)
