1. An ordered pair is a pair of numbers in parentheses, separated by a comma, which indicates the distance of a point from the origin. The first number represents the x-coordinate (where it is from side-to-side), and the second number represents the y-coordinate (where it is from up and down).
2. The four quadrants of the basic plane are listed in this order:
II | I | ========= | III | IV
A point in the first quadrant (I) <span>could be (5, 10), since that means that you would be moving right 5 and up 10.</span>
A point in the second quadrant (II) could be (-3, 6), since that means that you would be moving left 3 and up 6.
A point in the third quadrant (III) could be (-7, -1) since that means that you would be moving left 7 and down 1.
A point in the fourth quadrant (IV) could be (2, -6) since that means that you would be moving right 2 and down 6.
A point on the x-axis could be (9, 0) since that means that we are moving right 9 and making no vertical movement.
A point on the y-axis could be (0, 4), since that means that we are going up 4 and making no horizontal movement.
Area=legnth times width area=3/5 legnth=7/8 width=x 3/5=7/8 times x divide both sides by 7/8 (aka multiply both sides by 8/7 to cancel fraction because 7/8 times 8/7=56/56=1)
8/7 times 3/5=56/56 times x 24/35=1 times x 24/35=x
How many acres are there in 1 square mile? There are 640 acres in 1 square mile. To convert from square miles to acres, multiply your figure by 640 (or divide by 0.0015625) .
