Question

53 POINTS. Which expression gives the distance between the points (7, -2) and (3, -1)?
A.√4² +3²
B.√4² +1²
C. 10² +3²
D.√10² + 1²

Answer 1

the formula for distance between points is:

Distance = sqrt((x2-x1)^2 + (y2-y1)^2)

Using the points given:

Sqrt((3-7)^2 + (-1 - -2)^2)

Sqrt(-4^2 + 1^2)

None of the answer have a -4 but I think it should be B. Since it is the closest. Did you forget a negative sign when typing??

answer B.
