Answer:
a = 9
Step-by-step explanation:
expand (y - 3)(y² + 3y + 9)
= y³ + 3y² + 9y - 3y² - 9y - 27
compare the coefficients of like terms with
y³ + 3y² + ay - 3y² - ay - 27
ay = 9y and - ay = - 9y ⇒ a = 9
The slope intercept formula: y=mx + b
2y - 8x = 20 ∫ Add 8x to both sides to make the equation suitable∫
2y = 8x + 20 ∫Divide both sides by 2∫
∵ y= 4x + 10 ∵
