Find the slope of the line:
(1, -3/4) and (4,-3)​

m=-3/4

Step-by-step explanation:

y2-y1/x2-x1

-3-(-3/4)/4-1

-3+3/4/3    simplify -3+3/4 to -9/4

-9/4 /3       simplify 9/4 /3 to 9/4*3

-9/4*3

-9/12

-3/4

(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

-2 is the right
