Question

Point D has coordinates (8,3). Point G has coordinates (-4,3). What is the length of segment DG?

6 units
12 units
14 units
4 units

Answer 1

12 units

Explanation:

calculate DG using the distance formula

d =
`\sqrt{(x_(2)-x_(1))^2+(y_{2 -y_(1) } )^2`

with (x₁, y₁ ) = D (8, 3 ) and (x₂, y₂ ) = G (- 4, 3 )

DG =
`√((-4-8)^2+(3-3))^2)`

=
`√((-12)^2+0^2)`

=
`√(144+0)`

=
`√(144)`

= 12

Answer 2

Answer: 12 units

Explanation:

If you graph them on a graph you count the units between them and that is your anwser.
