What's the equation of the line that passes through the points (–1,5) and (1,–1)?

y = -3x + 2

Step-by-step explanation:

Use rise over run to find the slope of the line:

change in y / change in x:

-6 / 2

= -3

Plug in the slope and a given point into y = mx + b, and solve for b:

y = mx + b

5 = -3(-1) + b

5 = 3 + b

2 = b

Plug in the slope and b into y = mx + b:

y = mx + b

y = -3x + 2

So, the equation of the line is y = -3x + 2

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)
