3 22. inequality a mathematical sentence that uses <, >,,, or 7 > less than or equal to or more than or equal to quadrant 26 coordinate plane 27 ordered pair the x- and y- axes divide the coordinate plane into four regions called quadrants is formed by a horizontal number line called the x-axis and a vertical number line called the y-axis identifies the location of a point in the coordinate plane. The x-coordinate shows a points position left or right of the y-axis. The y-coordinate shows a point's position up or down from the x- axis (x, y) (over right or left, up or down) 28 origin the point of intersection of the x- and y- axes on a coordinate plane (0,0) 29 numerator 30 denominator the top number of a fraction that tells the quantity being considered the bottom number of a fraction that tells the total amount being considered 9/10 9 is how many pieces are being considered 9/10 10 tells how many althogether or how many pieces altogether
