Question

Use the coordinate grid to determine the coordinates of point P:

A coordinate grid shown from negative 2 to positive 2 on x-axis and negative 2 to positive 2 on y-axis. There are 4 grid lines between a whole unit of the grid. A point labeled P is shown at the intersection of 8 grid lines to the left of the y-axis and 4 grid lines above the x-axis.

What are the coordinates of point P?

(0.8, −0.4)
(−0.8, 0.4)
(1.6, −0.8)
(−1.6, 0.8)

Answer 1

Option D: $(-1.6,0.8)$ are the coordinates of the point P

Explanation:

It is given that "A coordinate grid shown from negative 2 to positive 2 on x-axis and negative 2 to positive 2 on y-axis. There are 4 grid lines between a whole unit of the grid".

Thus, the value of each grid is $0.2$

It is also given that, "A point labeled P is shown at the intersection of 8 grid lines to the left of the y-axis and 4 grid lines above the x-axis".

Since the point P lies on the left of the y-axis and above the x-axis, the x-value will be negative and y-value will be positive.

Thus, the value of x-axis is given by

$8\times0.2=-1.6$

And the value of y-axis is given by

$4\times0.2=0.8$

Thus, the coordinates of the point P is $(-1.6,0.8)$

Hence, Option D is the correct answer.
