Answer:
The gas Oxygen supports combustion, so in the environment where there was no lid covering jar 4, it's sure to receive a lot of oxygen
The missing exponent is 2
Y-8= 3(x+2)
Y-8= 3x + 6
+8. +8
Y= 3x +14
<h2>
Answer with explanation:</h2>
When there is a linear relationship is observed between the variables, we use linear regression predict the relationship between them.
Also, we predict the values for dependent variable by modelling a linear model that best fits the data by drawing a line Y=a+bX, where X is the explanatory variable and Y is the dependent variable.
In other words: The line of best fit is a line through a scatter plot of data points that best describes the relationship between them.
That's why the regression line referred to as the line of best fit.
