FIRST ONE TO GET RIGHT GETS 100 POINTS The graph shows the prices of different numbers of bushels of corn at a store in the current year.

The table shows the prices of different numbers of bushels of corn at the same store in the previous year.

Part A:
Describe in words how you can find the rate of change of a bushel of corn in the current year, AND find the value. (2.5 points)

Describe in words how you can find the rate of change of a bushel of corn in the previous year, AND find the value. (2.5 points)

Part B:
How many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? Show ALL your work! (5 points)

7x+8y=-18, 4x-9y=-3 solve the system of equations

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.

Select the correct answer from the drop-down menu. subtracting 3xy^2 from 8xy^2 gives the same result as the expression. [tex]3xy ^{2} - 8xy ^{2} [/tex][tex] { - 7xy}^{2} - {2xy}^{2} [/tex][tex] {7xy}^{2} - {2xy}^{2} [/tex]
