​ (−1,3) ​

​ (−5,−6) ​

​ (23,−74) ​

Answer 1

Answer:

The ordered pair that is on the line is​ (−5,−6) ​

Step-by-step explanation: You have to substitute...

Soooo....

(1,-32):

3x − 4y = 9

3(1) - 4(-32) = 9

3 + 128 = 9

131 = 9

NO

• Remember, a negative times a negative becomes positive.

(-1,3):

3x − 4y = 9

3(-1) - 4(3) = 9

-3 - 12 = 9

-15 = 9

NO

• Remember, a negative times a positive becomes a negative.
• Remember, a negative plus a negative becomes a negative.

(-5, -6)

3x − 4y = 9

3(-5) - 4(-6) = 9

-15 + 24 = 9

9 = 9

YES

(23, -74)

3x − 4y = 9

3(23) - 4(-74) = 9

69 + 296 = 9

365 = 9

NO
