. Find the slope of the line containing the points (3,-7) and (4,-9).

m=-2

Step-by-step explanation:

the formula for slope (m) is (y2-y1)/(x2-x1)

the given points are (3,-7) and (4,-9)

label the points;

x1=3

y1=-7

x2=4

y2=-9

substitute into the equation:

m=(-9--7)/(4-3)

m=(-9+7)/(1)

m=-2/1

the slope is -2

(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
