Is y = 2x + 4 a proportion relationship

*(revised answer)

So the answer is no, a proportional relationship has to run through the origin, and y=2x+4 has a y-intercept of 4, meaning that even though x increases when y does, the y-intercept means that this equation is not a proportional relationship.

Hope this helps!

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
