b
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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line
m = = = - 3
with m = - 3 and (a, b) = (3, - 5), then
y - (- 5) = - 3(x - 3), that is
y + 5 = - 3(x - 3) → b
