Which order pair could be a solution to this inequality
Tasya [4]

Answer:

(0,3)

Step-by-step explanation:

Given inequality is

y< x+ 4

to check the solution we plug in each ordered pair and check with our inequality

Lets check (-1,4)

here x=-1  and y =4

We plug in -1 for x  and 4 for y in our inequality y<x+4

4 < -1 + 4

4 < 3 that is false, so (-1,4) is not our solution

Now we plug in (0,5), x=0  and y = 5

y < x+4

5 < 0 + 4

5<4  that is false, so (0,5) is not our solution

Now we plug in (0,3), x=0  and y = 3

y < x+4

3 < 0 + 4

3<4  that is true,  so (0,3) is our solution
