The answer is 10 ft. make a triangle 6ft tall, 8ft long (90 degrees to the other line) and draw a line to complete the triangle. This is a type of 3,4,5 triangle, a 6,8,10. The other way to do it is sqrt(6^2+8^2) = sqrt(36+64) = sqrt (100) = 10.
The answer
for such a question, it is required to graph each function, the answer is

Answer: -2/3</h3>
==========================================
Work Shown:
Use the slope formula to get
m = (y2 - y1)/(x2 - x1)
m = (-3 - 5)/(5 - (-7))
m = (-3 - 5)/(5 + 7)
m = (-8)/(12)
m = -2/3
