  -1/2 = -0.5

Step-by-step explanation:

The slope magnitude is correct: there is a vertical change of 5 units for each horizontal change of 10 units. However, the vertical change is negative, so the slope is ...

  m = ∆y/∆x = -5/10 = -1/2 = -0.5

(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
