The regression line is y = 10x + 125, and the value of calories is 135, and when x = 12 the value of y = 245 from the regression line, butbut the actual value is 225.
What is the line of best fit?
A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dot's relationship.
Here the scatter plot is not given, but we can draw the scatter plot using the data which is given with two variables such as (x, y) and the line which is best fit of the given data.
From the data given, we can write the line of best fit in slope and y-intercept form:
y = mx + b
Plug m = 10 and b = 125
y = 10x + 125
The number of fat grams in an item having that number of fat calories.
As we have the regression line:
y = 10x + 125
Put x = 1 in the regression line:
y = 10(1) + 125
y = 135 calories
For x = 12
y = 10(12)+125 = 245
But the actual value from the graph is 225.
Thus, the regression line is y = 10x + 125, and the value of calories is 135, and when x = 12 the value of y = 245 from the regression line, but but the actual value is 225.
