Answer:
A.
Step-by-step explanation:
Slope = y2-y1/x2-x1
(2,-4) = (x1,y1)
(4,2) = (x2,y2)
Slope = (2+4)/(4-2)
= 6/2
= 3
Y=mx+b [Plugging (4,2) into this]
2 = 3×4 +b
2 = 12 + b
b = -10
Answer:
1 pencil will be for 1.75 $
Y = mx + c
y = (1/2)x + (-2)
<span>y = (1/2)x - 2

C
Answer:
362880 ways
Step-by-step explanation:
The word dragonfly has 9 different letters.
So, to find how many ways this word can be arranged, we just need to calculate the factorial of 9:
First letter has 9 possibilities
Second letter has 8 possibilities (one used)
Third letter has 7 possibilities (two used), and so on.
So the number of ways is:
9*8*7*6*5*4*3*2*1 = 362880 ways
