Use the scatterplot and line of best fit shown to
complete the statements.
When x = 5,
the observed value is blank
the predicted value is blank
the residual is blank

For this case we have that the trend line goes through the following points:

"A line of best fit passes through the y-axis at 1 and through the point 4 and 3"

That is, it goes through:

(0, 1)

(4, 3)

The equation of the line is:

y = mx + b
  

Where,

b = 1
  

The slope is:

m = (y2-y1) / (x2-x1)
 
 m = (3-1) / (4-0)

 m = (2) / (4)

 m = 1/2

Substituting values:

y = (1/2) x + 1


The equation of this line of best fit in slope-intercept form is:

y = one halfx + 1

Step-by-step explanation:

the observed value is 9

the predicted value is 7

the residual is 2
