Calculate the slope of the trend line
Please... :(

Slope is .18

Step-by-step explanation

Find two points along the line.

Calculate slope using .

I used the points (1985, .21) and (1990, .30).

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
