A scientist created a scatter plot to display the height of a plant over a 12-day period. Which is the equation of the trend line that is shown

y = (4/7)x + 1/7

Step-by-step explanation:

In the picture attached, the plot is shown.

The trend line pass through points (5, 3) and (12, 7). Its slope is:

m = (y2 - y1)/(x2 - x1) = (7 - 3)/(12 - 5) = 4/7

The general equation of a line is:

y = mx +b

Replacing with the coordinates of one of the points and with the slope, we get:

3 = (4/7)5 + b

b = 3 - 20/7

b = 21/7 - 20/7

b = 1/7

for any of you who need the translation here it is

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
