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 =
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (3, 4) ← 2 points on the line
m = =
= -
the line crosses the y- axis at (0, 5 ) ⇒ c = 5
y = - x + 5 ← equation of line
