<span>The slope of the line is equal to (y - 7) / (x - 4)
Then we can set up this equation:
(y - 7) / (x - 4) = 3
y - 7 = 3 * (x - 4)
y - 7 = 3x - 12
y = 3x - 5
This is the equation of the line.</span>
The y/x values all have the same ratio, 2/5. The line is
y = (2/5)x
Using Pythagorean theorem, the answer should be 8.7ft
