-3/2

Step-by-step explanation:

slope is rise over run. you read a graph like a book, left to right. So you go down three and right 2 from the first point to the second point. that means the slope is -3/2

 the answer is could be -2/3 or 2/3

Step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
