Question

URGENT NEED HELP. What is the approximate length of AB?

Answer 1

Approximate length of AB is 9.2 units.

Explanation:

You can use Pythagorean Theorem (check out the picture below) or directly use the distance formula.

Pythagorean Theorem

`\text{hypotenuse}^2 = \text{leg}_1^2 + \text{leg}_2^2`

Hypotenuse is AB and you can read the length of the legs from the graph.

`\text{AB}^2 = 6^2 + 7^2\\\text{AB}^2 = 85\\\text{AB} = √(85) \approx 9.2195\\\text{AB} \approx 9.2`

Another way to do it is to use the distance formula.

The Distance Formula

`\text{The distance between two points } (x_1, y_1) \text{ and } (x_2, y_2) \text{ is given by the formula:}\\d = √((x_2-x_1)^2 + (y_2-y_1)^2)`

You can read the points from the graph:

A(-2,-3)

B(4,4)

`d = √((-2-4)^2 + (-3-4)^2)\\d = √(36 + 49)\\d = √(85) \approx 9.2`

You can see that both ways give the same answer. Use whatever you prefer.

Answer 2

Answer: 8.5 maybe
