Hey there!
Guide:
• Negatives are BELOW 0
• Negatives are SMALLER than 0
• Negatives are also on the LEFT side of 0.
• Positives are ABOVE 0
• Positives are BIGGER than 0
• Positives are also on the RIGHT side of 0.
Thus, this means 7 is bigger than -9 because, your -9 is a negative number and 7 is a positive
That being said 7 > -9 (7 is the greater number out of the two numbers)
Good luck on your assignment and enjoy your day!
