HELP The slope of a line is 2 and the point (1, 1) lies on the line. What is the y-intercept of this line?

-1

Step-by-step explanation:

What you're gonna do is plug in the values. (i rhymed) The formula is y=mx+b

m = slope

b = y-intercept

y and x are just the y and x values.

1 = 2(1) + b

1 = 2 + b

-2   -2    

-1 = b

That's how you solve for the y-intercept (b) = -1.

Hope this helps and have a great day!

(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
