Question

Point P on the coordinate grid below shows the location of a stage light. A second stage light is 8 units above P. The length of each square on the grid is 2 units. What are the coordinates of the location of the second stage light?

point p is 4,-2

Answer 1

Add 8 to the y value of point p, (4, -2 +8)

So the location of the second light is on point (4,6)

Answer 2

(4, 6)

Explanation:

Given,

The coordinates of P in the grid are,

(4, -2)

If the second stage light is above P,

Let the coordinates of second stage light, say Q,

( 4, -2 + y)

Since, Q is 8 unit above P,

That is,

y = 8

Hence, the coordinates of Q or the coordinates of the location of the second stage light are,

( 4, -2 + 8 )

= ( 4, 6 )
