Answer:
On a coordinate plane, a straight line with a positive slope begins at point (0, 0), and ends at point (2.5, 5)
Step-by-step explanation:
The distinction between "straight line" and "blue diamonds" is that the straight line represents the relation for all possible values of x. The blue diamonds show the values of y for very specific values of x.
Since x is the amount of rice from a bulk bin, we assume it can take any non-negative value. Hence, the graphs with negative values or with "blue diamonds" are not appropriate.
The straight-line graph in the first quadrant is the best choice.
Answer:
9 Superscript negative 3
Step-by-step explanation:

X+y=23 (x and y added equal the number of baskets made)
2x+3y=53 (since each basket is worth a certain amount of points, x and y must be multiplied by their amount of baskets and added together to get the total number of points)
Hope this helps!
Assuming all of them had the same amount at the start
-13 c I think. It is this way because if it went down 15, then you subtract 2-15. 2-2 = 0, and then 0-13= -13 c. Hope this helps
