Question

What is the distance between the points -1 ,8 and 7,8
in the coordinate plane

Answer 1

Answer: 8 units

Explanation:

To find the distance between 2 points, we want to use the formula
`d=√((x_2-x_1)^2+(y_2-y_1)^2)`. Since we are given the 2 points, all we have to do is plug them in.

`d=√((7-(-1))^2+(8-8)^2)` [parenthesis]

`d=√((8)^2+(0)^2)` [exponent]

`d=√(64+0)` [add]

`d=√(64)` [square root]

`d=8`

Now, we know the distance is 8 units.
