Answer:
[tex]\sqrt{118}[/tex] or 10.8627805
Step-by-step explanation:
Start by taking the difference of each value of both points
Find the difference in x values
78-2 = 76
Find the difference in y values
46-4 = 42
Add the two differences
76+42=118
Take the square root of this value
[tex]\sqrt{118}[/tex]
