The formula Yvette needs to use to find the distance between the points are C(1, 2) and D(7, 10) is [tex]= \sqrt{(10-2)^{2}+(7-1)^{2}}[/tex].
What is the distance between two points in a coordinate plane?
The distance between two points in a coordinate plane [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] is
[tex]= \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
Here the given points are C(1, 2) and D(7, 10).
Therefore, the formula Yvette needs to use is
[tex]= \sqrt{(10-2)^{2}+(7-1)^{2}}[/tex]
