100 Points + Brainliest! I need the slops of these 3 coordinates! 1 What is the slope of line segment PQ with coordinates P(-2,5) and Q(-1, 1)?

2 What is the slope of line segment QR with coordinates Q(-1, 1) and R(7,3)?

3 What is the slope of line segment PR with coordinates P(-2, 5) and and R(7,3)?

What is the standard deviation of the following data set rounded to the nearest tenth? 3, 17, 18, 15, 12, 21, 9

If you could answer these your a life saver

❤️ (geometry) does the construction demonstrate how to copy an angle correctly using technology a) yes; the distance between points a and f was used to create circle h b) yes; the distance between points f and g was used to create circle h c)no; the distance between points a and f was used to create circle h d) no; the distance between points f and g was used to create circle h
