Question

The slope of TX is 2/7 and

TX||CH


What is the slope of CH


-7/2


-2/7


2/7


7/2

Answer 1

`k:\ y=m_1x+b\\l:\ y=m_2x+c\\\\If\ l\ ||\ k\ then\ m_1=m_2`
Therefore

`If\ TX:\ y=(2)/(7)x+b\ and\ TX\ ||\ CH\ then\ CH:\ y=(2)/(7)x+c`
Answer: 2/7

Answer 2

If those segments are parallel to each other then their slopes are exactly the same. So 2/7
