Answer:
Bryan spent $45 on flowers. The last sentence isn't needed to answer this question.
Step-by-step explanation:
If you multiply 10 by 2, then 5 by 5, and add it at the end you get 45.
-5
a=4 and b=-1
2(4)+3(-1)= 5
m=2
slope is the average rate of change in a specific interval
we can calculate slope in this case with Δy/Δx or (y2-y1)/(x2-x1)
m=(y2-y1)/(x2-x1)
=(-1-7)/(-3-1)
=-8/-4
=2
B-1, C-2, A-3
=5
