Question

What is the length of side AC as shown on the coordinate plane? On a coordinate plane, a rectangle has 4 points. Point A is (negative 2, 1), point B is (4, 1), point C is (negative 2, negative 3), and point D is (4, negative 3). 1 units 3 units 4 units 6 units

Answer 1

4 units

Explanation:

Answer 2

The length of side AC is 4 units

Explanation:

Find the diagram in the attachment below.

In order to determine the length of side AC, we will use the formula for calculating the distance between two points as shown;

`D = \sqrt{(x_2-x_1)^(2) + (y_2-y_1)^(2)}`

For side AC with A (-2, 1) and C (-2, -3)

x1 = -2, y1 = 1, x2 = -2, y2 = -3

`AC = D = \sqrt{(-2-(-2))^(2) + (-3-1)^(2)}\\AC = \sqrt{0^(2) + (-4)^(2)}\\AC = √(16) \\AC = 4`

The length of side AC is 4 units
