Answer:

(-1,\frac{17}{6})

(3,\frac{3}{2})

(-5,\frac{25}{6})

Step-by-step 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,\frac{17}{6})) we put x=-1 and y=\frac{17}{6} to get

2(-1)+6*\frac{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.

That would be A :D It would be A because you would do keep change flip. You would keep 5/6, change the division sign to multiplication, then flip the 5/16 to 16/5 (the reciprocal)
