SOLUTION: 1)y=-x-12 (-7, ) a)(-7,-5) b)(-7,5) c)(-7,-9) d)(-7,9) 2) y=-x+1 (-4, ) 3) 36x+9y=15 (4/9, )

Question 617983: 1)y=-x-12 (-7, )
a)(-7,-5) b)(-7,5)
c)(-7,-9) d)(-7,9)
2) y=-x+1 (-4, )
3) 36x+9y=15 (4/9, )

1)

y = -x - 12 (-7,  )

We substitute (-7) in place of x and we have

y = -(-7) - 12

y = +7 - 12

y = -5

So we put -5 in the space of (-7,  ) and get

            (-7,-5)

Correct choice is b)
