Answer: -0.5 and 5.1
Step-by-step explanation
The midpoint formula is: m = (a+b)/2
For example, the midpoint of 4 and 8 is 6 because
m = (a+b)/2 = (4+8)/2 = 12/2 = 6
Here are the five answer choices:
- -2.3 and 2.3
- -2.3 and 4.6
- -1 and 3
- -0.5 and 5.1
- -0.3 and 3.3
Go through each answer choice to use the midpoint formula. The goal is to get m = 2.3
Try out the first answer choice and we get (-2.3+2.3)/2 = 0, so we can rule it out.
Repeat for the other answer choices.
The answer is -0.5 and 5.1 because: (-0.5+5.1)/2 = 2.3
Use a number line to help confirm the answer is correct.
