An equation for the line of best fit is y = -0.3x + 4.5 and the value of "m" is -0.3.
<h3>What is a line of best fit?</h3>
A line of best fit simply refers to a statistical tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any association (correlation) between data points.
In this scenario, the ordered pairs would be plotted on the x-coordinate and y-coordinate of a scatter plot.
By critically observing the scatter plot (see attachment) which models the ordered pairs, we can reasonably and logically deduce that a linear function for the line of best fit is given by:
y = -0.3x + 4.5 ≡ y = mx + b
<u>Where:</u>
- -0.3 or m represents the slope.
- x and y are the points.
- 4.5 or b represents the y-intercept.
Therefore, m is equal to -0.3.

Ok, so, let me draw a graph....... ok, so this is actually pretty easy. i believe that you are talking about what is the name of the slope it forms when i put those two points together. when you connect<span> (3,-6) and (-1,2)</span>, you get a "Down- hill" slope or we call it also a negative slope, because the line points down hill!
******thanks so much!!!! please mark as brainliest if possible!!!!!! i really need the points!!!! thank you!!!!
If x is the first number, x+2 is the next consecutive even integer. The difference (subtraction) of their squares equals 20. Therefore:
(x+2)²-x²=20...expand this:
x²+4x+4-x²=20
x²+4x+4-x²=20
4x+4=20
4x=16
x=4. Therefore the next consecutive even integer is x+2=6.
To check: 6²-4² must equal 20
36-16=20 check!
Answer: 38.19
Step-by-step explanation: Well I like to find 1% first, so I would do 1,200/100. This equals 10.91.
But now seeing as we want 3.5%, we would multiply 10.91 by 3.5. This would give us 38.19 (or 38.18 if you don't round up)
hope this helps and i hope i understood your question correctly
