What is the slope of the line described below? y-9=15(x-5)

slope = 15

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)

y - 9 = 15(x - 5) is in this form

thus slope = m = 15

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
