What is the slope of the line shown below? (-7,2) (4,6) The answer is 4/11

_4_
11

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0

Angles r and s are complementary. the measure of angle r is 31 degrees. which equation can be used to find angle s?

Can someone answer this question for me
