Plot the following points in the cartesian plane whose x, y coordinates are given.
x | 2 | 3 | -10 | -9 | -4 |
---|---|---|---|---|---|
y | -3 | -3 | 41 | 10 | -6 |
Solution
The x and y coordinates of the points have been given individually. We convert them in the form of (x,y). The distances are from the origin. The x coordinate defines the distance of the point from the origin along the Y-axis. Same goes for y points. We plot those points in the graph according to their distance.
Complete step-by-step answer:
We have been provided with points on cartesian coordinates in the form of (x,y).
Given all points will be turned into the form of (x,y) where the distances are from the origin. The x coordinate defines the distance of the point from the origin along Y-axis.
The y coordinate defines the distance of the point from the origin along X-axis.
Now we plot all these points on the graph.
Let’s take every point one by one to find their positions. In every case we start from origin.
(x,y)=(2,−3). Here, the x-distance is 2 units in a straight line along the X-axis from the Y-axis and the y-distance is 3 units in a straight line along the negative Y-axis from X axis.
(x,y)=(3,−3). Here, the x-distance is 3 units in a straight line along the X-axis from the Y-axis and the y-distance is 3 units in a straight line along the negative Y-axis from X-axis.
(x,y)=(−10,41). Here, the x-distance is 10 units in a straight line along the negative X-axis from the Y-axis and the y-distance is 41 units in a straight line along the Y-axis from the X-axis.
(x,y)=(−9,10). Here, the x-distance is 9 units in a straight line along the negative X-axis from the Y-axis and the y-distance is 10 units in a straight line along the Y-axis from the X-axis.
(x,y)=(−4,−6). Here, the x-distance is 4 units in a straight line along the negative X-axis from the Y-axis and the y-distance is 6 units in a straight line along the negative Y-axis from the X-axis.
Note: We need to remember that the unit distance is fixed along both axes. Although we are finding the distance from origin, we are not finding the straight-line distance. For the straight-line distance, we have to apply Pythagoras’ theorem. We have a point (x,y). Then the straight-line distance will be x2+y2 unit.
