4.00
Step-by-step explanation:
Given
x: 2 , 5 , 8 , 12
y: 8.50, 15.25, 22.00. 31.00
Required
Determine the y intercept
First, we calculate the slope:

Where





Next, we calculate the equation:

Where:

The equation becomes:


Make y the subject


Take
; to get the y intercept


<em>Hence, the y intercept is 4.00</em>
The range is (-1,∞),{yly>-1}
