Two students were asked to graph the rational number -7.1. amy states that the number is between -8 and -7, but laura states that the point is between -7 and -6. how can you determine which student is correct?

Amy is correct, -7.1 is between -7 and -8.  We know this because in order for it to be in between -6 and -7, the number would have to be a decimal with a whole number of 6 (for example, 6.3 or 6.7).  But -7.1 has a whole number of 7 so it is in between -7 and -8

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
