Question

Find the distance between points (1, -4) and (1, 0)
-4
4
0
3

Answer 1

do you know the distance formula?

Answer 2

Distance between points (x1,y1) and (x2,y2) is
\(\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\)
does this help ??

Answer 3

True. Great formula.

But notice that x does not change from the first point to the second.
Thus, we can find the distance between the 2 points without using the distance formula.

Answer 4

when one co-ordinate is same, the distance is just the difference between other co-ordinate

Answer 5

0-(-4)= ...

Answer 6

4

Answer 7
