Answer:
B
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 ) = (0, 2) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m = [tex]\frac{1-2}{1-0}[/tex] = - 1
note the line crosses the y- axis at (0, 2) ⇒ c = 2
y = - x + 2 → B
