Answer:
y = - 
 x + 3
 x + 3
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 = 

with (x₁, y₁ ) = (2, 0 ) and (x₂, y₂ ) = (0, 3 )
m = 
 =
 = 
 = -
 = - 

The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - 
 x + 3 ← equation of line
 x + 3 ← equation of line
