Answer:

(y - 3)(y - 5)

Step-by-step explanation:

Consider the product of the factors of the constant term which sum to give the coefficient of the y- term

product = + 15, sum = - 8

The factors are - 3 and - 5

y² - 8y + 15 = (y - 3)(y - 5)

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

const2013 [10]

Answer:

y + 12 = 3(x - 2)

Step-by-step explanation:

Insert the coordinates into the formula with their CORRECT signs. Remember, in the Point-Slope Formula, y - y₁ = m(x - x₁), all the negative symbols give the OPPOSITE term of what they really are. Since both lines contain have to have similar rate of changes [slopes], we do not go any further.
