Answer: 1) You forgot to change the sign over there. You have to subtract over there.
2) Just be careful while solving equations while changing the signs

Answer:
C
Step-by-step explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line
m = =
= - 2
using (a, b ) = (2, - 1 ) , then
y - (- 1) = - 2(x - 2) , that is
y + 1 = - 2(x - 2)
