Write an equation in point-slope form for the line through the given point with the given slope (9,-1) ; m=4/5

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = and (a, b) = (9, - 1), hence

y - (- 1) = (x - 9), that is

y + 1 = (x - 9) ← in point- slope form

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

(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
