I Just took the test. 100%, 8/8.
For number 3 and 6, you can simply test solutions by substituting each of the x and y coordinates for x and y in the equation.
The Zodiac Killer is right. 100% 8/8
All of these are correct, except 6 and 3, which are: 3: B. 6: Look at Steve's answer.
@The Zodiac Killer (Ted Cruz) is correct!
The Zodiac Killer (Ted Cruz) still correct for full quiz "Unit 2 Functions Lesson 9 Systems of Equations" 2022 :)
The Zodiac Killer is correct. 8/8 100%
Zodiac Killer is correct!!
thx so much zodiac killer :3 xoxoxoxox
