Question

Find the distance between the two points rounding to the nearest tenth (if necessary). (-7, 0) and (-3, 8)

Answer 1

Answer: 8.9 units

Explanation:

We can use the distance formula for a 2d plane:

distance = √
`(x_2 - x_1)^2 + (y_2 - y_1)^2`

Plugging in our values for x1, y1, x2, and y2:

x1 = -7

y1 = 0

x2 = -3

y2 = 8

√
`(-3 - -7)^2 + (8 - 0)^2`

= √
`(4)^2 + (8)^2`

= √
`16 + 64`

= √
`80`

=
`8.944271921`

= 8.9 rounded to the 10th
