Question

Find the distance between A and B.A. 4V5 unitsB. 10 unitC. 9 unitsD. 782 units

Answer 1

The question requires you to find the distance between points A and B

Point A {-4,-1} and B {5,0}

Apply the formula for length between two points given coordinates;

`d=\sqrt[]{(x_{2-x1)^2\text{ +}(y2-y1)^2}_{}}`

Use the values in the equation as;

`d=\sqrt[]{(5--4)^2+(0--1)^2}`

This will give the following;

`d=\sqrt[]{9^2+1^2}`
`d=\sqrt[]{81+1}`
`d=\sqrt[]{82}\text{ units}`

Answer : D
