Question

Which ordered pairs are Solutions to the inequality y-3x<-8? Select each correct answer.

Answer 1

Answer:

(5,4) and (0,-9)

Step-by-step explanation:

We are given that an inequality

$y-3x$

We have to find the ordered pair of solution of given inequality.

1.(5,4)

Substitute x=5 and y=4 then we get

$4-3(5)=-11 < -8$

It is a solution of given inequality because it satisfied the given inequality.

Hence, it is true.

2.(0,-9)

Substitute the values then we get

$-9$

It is a solution of given inequality because it satisfied the given inequality.

Hence, it is true.

3.(-3,-2)

Substitute the values then we get

$-2-(-3)(3)=-2+9=7 >-8$

It is not true because it does not satisfied the given inequality.

4.(2,-1)

$-1-3(2)=-1-6 =-7 > -8$

It is not true because it does not satisfied the given inequality.

5.(1,-5)

$-5-3(1)=-5-3=-8\nless -8$

It is not true because it does not satisfied the given inequality.

Answer 2

Answer:

the correct answer Is (5,4), (0,-9)

Step-by-step explanation:

when x = 5 and y=4    the inequality  4-3(5)<-8   so : -11  < -8.....right  

when x = 0 and y=-9    the inequality  -9-3(0)<-8   so : -9  < -8.....right
