Question

3. Line segment AB has one endpoint at (1,2). Which of the below could represent the coordinates of the other endpoint of AB where the distance is 5? A (6,7) B 1,3) C1-3.1) D 16.-3)

Answer 1

Endpoint = (1,2)

distance = 5

Second endpoint

I think the answer is letter A, (6,7) let's check it

`\begin{gathered} \sqrt[]{(6-1)^2+(7-2)^2} \\ \sqrt[]{(5)^2+(5)^2} \\ \sqrt[]{25\text{ + 25}} \\ \sqrt[]{50} \end{gathered}`

ok, but do you have a picture of this question?

please upload it

To graph (1, 2) when the two lines cross, count 1 unit to the right, and from that point, count two units up. right and up is for positive numbers.

You must count the fiirst number in the horizontal line, and the second number in the vertical line.

I'll try the point (6, -3) this point is not the answer

distance = squared root (6 - 1)^2 + (-3 - 2)^2

5^2 + 5^2

Point (-3, 1) this point is not the answer

(-3 - 1)^2 + (1 - 2)

16 - +1

(1, -3) This point is the answer

(1 - 1)^2 + (-3 - 2)
