Answer:
C
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 = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = 2, 3) and (x₂, y₂ ) = (0, - 1)
m = [tex]\frac{-1-3}{0-2}[/tex] = [tex]\frac{-4}{-2}[/tex] = 2
The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1
y = 2x - 1 → C
