Answer: d= √(74)
Step-by-step explanation:
the distance formula is:
d = √((x2 - x1)^2 +(y2-y1)^2) . (all of that is under sq. root)
I do it i my head to make it much easier:
the distance from 4 to -1 is 5
and the distance from -5 to 2 is 7
so in your paper it should look like
d = √(5^2 + 7^2)
d= √(25+49)
d= √(74)
this can't be simplified so that is the answer.
