Points A and B have the coordinates shown below. Estimate the length of AB to the nearest tenth of a unit.
A= (-4,7)
B= (-12, -10)
AB = units

Distance AB is 18.79 units

Step-by-step explanation:

Given two points with coordinates as:

A= (-4,7)

B= (-12, -10)

To find:

Distance AB = ?

Solution:

To find the distance between two points with given coordinates, we can use Distance formula.

Distance formula  is given as:

where and are the two coordinates whose distance is to be find out.

Distance AB is 18.79 units

AB = 18.8 units

Step-by-step explanation:

If there are two points (x1,y1) and (x2,y2) on the coordinate plane.

distance between those two points =

given points are

A= (-4,7)

B= (-12, -10)

Thus, length of AB is 18.79 units

since, value of hudredth of unit is 9 which is greater than 9 then rounding the value to nearest tenth of unit we increase the value at tenth of unit place by that is 7 becomes 8

length of AB  to the nearest tenth of a unit is 18.9 units
