Question

Henry counted units to find the distance between two points. For which pair of points could he have done this ? Select all that apply.

Answer 1

(-3,5) & (-2,5)

(5,3) & (9,3)

(2,3) & (7,3)

Explanation:

Answer 2

Options:

(–3, 5) and (–2, 5) (–3, 5) and (–9, 3)

(5, 3) and (9, 3) (5, –9) and (3, –5)

(2, 3) and (7, 3)

Answer:

(–3, 5) and (–2, 5)

(5, 3) and (9, 3)

(2, 3) and (7, 3)

Explanation:

To do this, have to compare the both x and both y coordinates of the points.

If the x coordinates are equal or the y coordinates are equal, then that option is true

For (a): (-3,5) and (-2,5)

The y coordinates are the same:

i.e.

`y_1 = y_2 = 5`

This option is true

For (b): (-3, 5) and (-9, 3)

None of the coordinates are the same;

i.e.

`x_1 \\e x_2`

`y_1 \\e y_2`

Hence, this option is false.

For (c): (5, 3) and (9, 3)

The y coordinates are the same:

i.e.

`y_1 = y_2 = 3`

This option is true

For (d): (5, -9) and (3, -5)

None of the coordinates are the same;

i.e.

`x_1 \\e x_2`

`y_1 \\e y_2`

Hence, this option is false.

(2, 3) and (7, 3)

The y coordinates are the same:

i.e.

`y_1 = y_2 = 3`

This option is true
