Finding the Coordinates of a Point on a Coordinate Plane | Math with Mr. J

welcome to math with Mr Jay [Music] in this video I'm going to cover how to identify or how to find the coordinates of a point on a coordinate plane now just as a quick review remember the x-axis is the horizontal axis so it goes side to side this is the x-axis right here and then the y-axis is the vertical axis so it goes up and down this is the y-axis right here now remember the x coordinate always comes first and the y-coordinate always comes second let's jump into our examples starting with number one where we have point a so we need to find the coordinates of point a what's the x coordinate and what's the y-coordinate so when working with coordinates we always work horizontally first so we need to take a look at the x-axis and where point a is along among the x-axis so if we take a look at point a point a is right here along the x-axis and that's negative eight so that's going to be the x coordinate now we need to find the y coordinate so how far up is a well this is 5 on the y-axis so it's over to negative 8 and then up 5. so 5 is the y coordinate so the coordinates or ordered pair for point a negative 8 is the x coordinate and then 5 is the y coordinate so we have X and then y let's move on to number two where we have point B so let's determine the x coordinate first so where along the x-axis is B well right here which is nine so the x coordinate is nine now we need to figure out the y coordinate so how far down from 9 is B well this is negative 10 on the y axis so we go over 9 and then down to negative 10. so negative 10 is the y coordinate so the coordinates or ordered pair 9 negative 10. let's move on to number three where we have Point C and we're going to start with the x coordinate so we're along the x-axis is point C well right here which is negative 4. so that's the x coordinate as far as the y coordinate point C Is Right Here along the y-axis and that is 8 so the y coordinate is eight so we go over to negative four which is the x coordinate and then up 8. so 8 is the y coordinate so for Point C we have negative four eight let's move on to number four where we have Point D so we will start with the x coordinate point D is right here which is at 3 on the x-axis so the x coordinate is going to be 3. now as far as the y coordinate we are at zero on the y-axis we did not move up or down vertically so our y coordinate is zero so for D the x coordinate is three and the y coordinate is zero let's move on to number five where we have Point e and we will start with the x coordinate e is right here along the x-axis so the x coordinate is seven and then as far as the y coordinate e is right here along the y-axis so we go over 7 and then up 9 for Point e so those are the coordinates the x coordinate is seven and then the y coordinate is nine lastly let's move on to number six where we have Point f as far as the x coordinate f is right here along the x-axis which is negative 2. so the x coordinate is negative two as far as the y coordinate f is right here along the y-axis that's negative 2 as well so the y coordinate is also negative two so for the coordinates for Point F or the ordered pair the x coordinate is negative two and the y coordinate is negative two so we have negative two negative two so there you have it there's how to find the coordinates of a point remember the x coordinate always comes first and then the y coordinate always comes second I hope that helped thanks so much for watching until next time peace thank you
