Question

What is the distance between the points (-4, 2) and (1, -3) on the coordinate plane?

A. 7.07 units
B. 2.83 units
C. 5.83 units
D. 7.21 units

Answer 1

A. 7.07 units

Explanation:

Use the distance formula for coordinates:

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

Fill in the coordinates accordingly:

`d=√((1-(-4))^2+(-3-2)^2)`

which simplifies down to

`d=√(25+25)`

which is of course

`d=√(50)`

Plug that into your calculator and you'll get the answer
