The required equation that represents the line of best fit is y = 2x + 4

<h3>Finding the equation of a line of best fit.</h3>

A line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points.

From the given scatters plot, we only need to choose two points that aligns properly and create an equation of a line using the coordinates.

Using the following points (4, 12) and (2, 8)

The equation of the line will be in the form y = mx + b

where

m is the slope

b is the y-intercept

<u>Determine the slope</u>

Slope = y2-y1/x2-x1

Slope = 8-12/2-4
Sope = -4/-2
Slope = 2

<u>Determine the y-intercept</u>

Using the coordinate point (2, 8) and m = 2

8 = 2(2) + b

b = 8 - 4

b = 4

Hence the required equation that represents the line of best fit is y = 2x + 4

1. Gold has a higher density than silver. This is shown by the equation D = M/V, where D is density, M is mass, and V is volume. This means that when the jeweler put an equal amount of mass in, he had to put a greater volume of silver to equal the same mass of gold. The total volume of the crown increased.

2. Archimedes discovered that the amount of volume he put in (whether his body, or the crown) would be equal to the rise in volume of the water level (that is, the new water level versus the old one before anything had been put in). Archimedes would have then gotten a block of gold that weighed the same as the crown and checked the volume rise. Then once he tested the crown, he would have seen that the volume rise was higher than expected, and he would know that the jeweler had included some silver.

The length of a rectangle is 3 centimeters longer than the width. The perimeter of the rectangle is less than 15cm.
kozerog [31]

Answer:

15>4W+6

Step-by-step explanation:

Perimeter is:
P = 2(L+W)

15>2L+2W

L=W+3 = One length

2W+6= Both lengths

2W+2W+6=4W+6

4W+6 is perimeter

15>4W+6
