Chapter 2.6, Problem 44E

To determine

To describe: the location of the point.

Answer to Problem 44E

Here, $x-coordinate$ is negative 1, move 1 unit to the left. From here, since $y-coordinate$ is positive 2, move 2 units upwards.

Explanation of Solution

Given:

  $D\left(-1,2\right)$

Calculation:

To plot a point, starting from the origin, count the number of units going to the left or right. This is the first number in the ordered pair, the $x-coordinate$ (going to the left is negative and right is positive).

From the $x-coordinate$ , count the number of units going up or down. This is the second number in the ordered pair, the $y-coordinate$ (going down means negative and up means positive).

To plot the coordinates of $D$ , we start counting from the origin. Since, $x-coordinate$ is negative 1, move 1 unit to the left. From here, since $y-coordinate$ is positive 2, move 2 units upwards.

  

Conclusion:

Here, $x-coordinate$ is negative 1, move 1 unit to the left. From here, since $y-coordinate$ is positive 2, move 2 units upwards.
