Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

y = 3x - 18

Step-by-step explanation:

The line passes through (2,-12) and;

Its parallel to line y = 3x

The slope of our line is 3

Taking another point (x,y) on the line

Slope = change in y ÷ change in x

3 =

y + 12 = 3x - 6

y = 3x - 18

(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
