Based on the line of best fit, the length of this catfish can be predicted to be 38 inches.
<u>Given the following data:</u>
- Weight of catfish, x = 40 pounds.
<h3>What is a line of best fit?</h3>
A line of best fit is also referred to as a trend line and it can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any correlation between a data.
From the graph of the data, we have the following linear equation:

Substituting the value of x, we have:

y = 38 inches.

Answer:
x = 60
Step-by-step explanation:
The sum of the angles in a triangle is 180
40 + x+20 + x = 180
Combine like terms
2x+60 =180
Subtract 60 from each side
2x+60-60 =180-60
2x =120
Divide by 2
2x/2 =120/2
x = 60
(2, -1), (6,- 4), and (6, -1). Hope this helps man!
