What is the slope of the line? pls help me :(

-3

Step-by-step explanation:

pick two points where the line crosses exactly and make a triangle, for example (1,1) and (0,4)

difference in y ÷ difference in x = slope/gradient

difference in y = 4 - 1 = 3

difference in x = 0 - 1 = -1

= -3

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
