Question

2. For the graph, find AB to the nearest tenth y 8 А 6 B

Answer 1

Answer:

10.8

Step-by-step explanation:

AB can be calculated using the formula $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

The coordinates of A are when x = -2, y = -2

At B, x = 8, y = -6

Let,

$A(-2, -2) = (x_1, y_1)$

$B(8, -6) = (x_2, y_2)$

Plug the values into the formula.

$AB = \sqrt{(8 - (-2))^2 + (-6 -(-2))^2}$

$AB = \sqrt{(8 + 2)^2 + (-6 + 2)^2}$

$AB = \sqrt{(10)^2 + (-4)^2}$

$AB = \sqrt{100 + 16}$

$AB = \sqrt{116} = 10.8$ nearest tenth
