Need help here is an image so you can see what the question is asking

The missing value is the slope

let me be the slope

m= (3-1)/(0-(-1)) = 2

so y= 2x+3

the missing value is the y-intercept

wich the image of 0 *it's -1

so : y= 3x-1

draw the two functions

you'll find that they intercept at  (4;11)

(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
