we are asked to plot eight comma 10 so the first put the first number in this ordered pair this is our x-coordinate this tells us how far do we move in the x-direction it's a positive eight so we move eight in the x-direction so we move eight in the x-direction and then the second point or the second number in our ordered pairs ten that is our y-coordinate that tells us how far we move in the Y direction since it's positive we move up ten so we move up ten all the way over here and you could have thought about it either way you could have said hey look this is our y-coordinate this is ten so I could move up ten and then my x-coordinate is positive 8 so I'll move eight along the positive x axis or I'll move eight to the right you see right over here I have moved eight to the right one two three four five six seven eight and I have moved to 10 up one two three four five six seven eight nine ten you might be tempted to move eight up and then ten to the right which would put you there but then you would have had the two numbers mixed up you would have had the x and the y coordinates mixed up the eight tells you how far to move in the horizontal direction the ten tells you how far to move in the vertical direction let's do a couple more of these plot six comma 10 well once again and the the first number and the ordered pair is the x coordinate how far we move in the X Direction so we move six to the right and then the second number the 10 tells us our our vertical coordinate our y coordinate so it's positive 10 so we move 10 10 up let's do one more five comma seven so my horizontal coordinate is 5 so I move five to the right and then my vertical one is seven or my y coordinate is seven so I move seven up one two three four five six seven and as long as you remember which one is horizontal which one is vertical or which one is the x coordinate which one is the Y you should be fine you could say look this is my y coordinate seven so I'm going to move seven up and my x coordinate is 5 so I'm going to move five to the right and we'll get you to that exact same point this specifies exactly one point in the coordinate plane
