Answer:
y = -
x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (2, - 3) ← 2 points on the line
m =
= - 
Since the line crosses the y- axis at (0, 0 ) ⇒ b = 0
y = -
x ← equation of line
