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

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

where is the figure
