Subtract original amount from new amount:
84 - 39 = 45
He bought 45 books.
Parallel=same slope
Y=mx+b
Sub in the slope and point to solve for b
2=-6(-1)+b
2=6+b
2-6=b
-4=b
The equation is y=-6x-4; the answer is B
Hope this helps!
1/4 of 2,500 i hope you get it right
Answer:
Both slopes are as follows 1. 2 2. 2/5
Both equations are like
1.
16-12= 4
-----------=2
4-2= 2
=====
2.
10-4= 6
------------=2/5
20-5= 15
The Y intercept for both is as follows
1. 8
2. 2
I may be wrong on something but likely not and if I am sorry
