Question

Find the distance between the points (-4,-1) and (4,1). Round to 2 decimals places

Answer 1

Distance = 8.25 units

Explanation:

use the formula :

√ (x2 _ x1) + (y2 - y1)

where ,

x2 = 4

x1 = -4

y2 = 1

y1 = -1

Answer 2

length between is 8.54 units

Explanation:

Formular:

`{ \bf{ = \sqrt{ {(x_(1) - x_(2)) }^(2) + {(y_(1) - y_(2)) }^(2) } }}`

x1 is -4

x2 is 4

y1 is 4

y2 is 1

`= \sqrt{ {( - 4 - 4)}^(2) + {(4 - 1)}^(2) } \\ = √(64 + 9) \\ = √(73) \\ = 8.54 \: units`
