Which set of expressions are not equivalent? 3(3a) + a(3 a) and 3a² + 9 a

5(3 x) - 4(3 x) and 3x

4(3 a) - 2(4 a) and 4 a²

4 x( x) +3(2 x) and 4x² + 6 x​

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
