The equation of the straight line is y = -1/6(x - 10) + 4
<h3>How to determine the line equation?</h3>
The equation is given as:
y = 2x + 6
Linear equations are represented as:
y = mx + c
Where:
Slope = m
So, we have:
m = 6
The slopes of perpendicular lines are represented as:
n = -1/m
So, we have:
n = -1/6
The equation is then represented as:
y = n(x - x1) + y1
This gives
y = -1/6(x - 10) + 4
Hence, the equation of the straight line is y = -1/6(x - 10) + 4
