Question

Name.the point on DA whose distance from D is 2

Answer 1

you need to ubicate this point

Step 1

DA is a line that goes from D to A

Step 2

distance from D is 2,so move two unit to the left and to the rigth, it is D-2 and D+2 , those points are

`\begin{gathered} D=0 \\ D-2=0-2=-2 \end{gathered}`

now, see the character for -2

-2=B

now, let's see D+2

`\begin{gathered} D=0 \\ D+2=0+2=2 \end{gathered}`

the other point (2=F) does not work because it is not in the line DA

so, the answer is B
