Answer:

(-1,(17)/(6))

(3,(3)/(2))

(-5,(25)/(6))

Explanation:

The given equation is
2x+6y=15

We substitute the ordered pairs to see which ones satisfies the equation.

For (-1,-8), we put x=-1 and y=-8 to get:

2(-1)+6(-8)=^?15

$-2+-48=^?15\\-50=^?15$

This is not true.

For
(-1,(17)/(6))) we put x=-1 and
y=(17)/(6) to get

$2(-1)+6*(17)/(6))=15\\ -2+17=15\\15=15$

This is true

For (3,3/2) we have 2(3)+6(3/2)=15

This implies 6+9=15

15=15

This is also True

For (-5,25/6), we have 2(-5)+6(25/6)=-10+25=15

This is also true.
