Find the slope of the line that passes through (31, -16) and (23, 4).

Slope = change in y / change in x

(sometimes told as "rise over run" as y is up/down and x is left/right)  

What does that look like in an equation?

Solve:

So our answer is

Hope this helps, have a nice day :D

The answer is 5/-2 as I have attached the picture.

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)
