3/2 = 1.5

Let the value of the 1945 coin = x.
Then, the value of the 1950 coin = 1.5x

Together, they are worth $40. This gives us the equation:

x + 1.5x = 40

2.5x = 40

x = 40/2.5

x = 16

1.5x = 1.5 * 16 = 24

Answer: The 1945 coin is worth $16. The 1950 coin is worth $24.

What is the equation of this trend line?<br> RE<br> Enter your answers b y filling in the boxes.
Deffense [45]

Answer:

K=-2J+28

Step-by-step explanation:

step 1

Find the slope of the line

The formula to calculate the slope between two points is equal to

m=\frac{k2-k1}{j2-j1}

we have the points

(2,24) and (6,16)

substitute in the formula

m=\frac{16-24}{6-2}

m=\frac{-8}{4}

m-2

step 2

Find the equation of the line in slope intercept form

K=mJ+b

we have

m=-2

b=28 ----> the k-intercept is the point (0,28)  see the graph

substitute

K=-2J+28
