Sorry idkis it 34.55? I’m slow-
Percentage error

Here error = 16 - 15.4 = 0.6
Therefore, percentage error

=3.9%
The point-slope equation of the line is y - 8 = 3(x - 6)
<h3>How to determine the equation?</h3>
The points are given as:
(x1, y1) = (6, 8)
The slope is given as:
m= 3
The equation is then calculated as:
y - y1 = m(x - x1)
This gives
y - 8 = 3(x - 6)
Hence, the point-slope equation of the line is y - 8 = 3(x - 6)
