Find the slope of the line graphed

2/5

Step-by-step explanation:

We have two points so we can find the slope using

m = (y2-y1)/(x2-x1)

(-1,-1) and (4,1)

  m = (1 - -1)/(4 - -1)

      = (1+1)/ (4+1)

      = 2/5

2/5

Step-by-step explanation:

slope of a graph=

so the difference of y=1-(-1)=1+1=2

so the difference of x=4-(-1)=4+1=5

slope is 2/5

step-by-step explanation:

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)
