For this problem you can plug in the given values of x and y to the equation and see if its correct.
For the first one: 9(4)+2(-5)=13
36-10=26. 26 is not equal to 13 so your answer would be no.
For the second one: 9(0)+2(-8)=13
0-16=-16. -16 is not equal to 13 so your answer would be no.
For the third one: 9(1)+2(2)=13
9+4=13. 13 is equal to 13 (same number) so this would be yes.
For the fourth one: 9(3)+2(-7)=13
27-14=13. 13 is equal to 13 so this would be yes.
Answer:
No, no, yes, yes
Step-by-step explanation: All you have to do is plug in the x and y values.
9(4) + 2(-5) = 13
36 + -10 = 13
26 = 13
The first one is no.
9(0) + 2(-8) = 13
0 + -16 = 13
-16 = 13
The second one is no.
9(1) + 2(2) = 13
9 + 4 = 13
13 = 13
The third one is yes.
9(3) + 2(-7) = 13
27 + (-14) = 13
13 = 13
The fourth one is yes.
