It depends on what shape it is...
Answer:
y =
x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) =( 8, - 3) and (x₂, y₂ ) = (0, - 5)
m =
=
= 
Note the line crosses the y- axis at (0, - 5 ) ⇒ c = - 5
y =
x - 5 ← equation of line
Yeeeeeeeee ehehehehehehehehehej
arcsin(1/2) means "the angle whose sine is 1/2".
That's 30° .
y = cos(30°) = (1/2)√3 = about 0.866 .
