Answer:

∠a + ∠b + ∠c + ∠d = 360°

Step-by-step explanation:

What is the slope of this graph? −14 4 14 −4 Number graph ranging from negative 10 to 10 on both the x and y axis. A line passes
spin [16.1K]

The slope of this graph is - 4

Step-by-step explanation:

The slope of a line is m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} , where

  • (x_{1},y_{1}) and (x_{2},y_{2}) are two points on the line
  • The slope of a horizontal line is zero
  • The slope of a vertical line is undefined

∵ The graph is a line

∵ The line passes through points (1 , -2) and (0 , 2)

∴ x_{1} = 1 and x_{2} = 0

∴ y_{1} = -2 and y_{2} = 2

- Substitute these values in the rule below

∵ m=\frac{y_{2}-y_{1}}{x_{2}-x_{2}}

∴ m=\frac{2--2}{0-1}=\frac{4}{-1}

∴ m = - 4

The slope of this graph is - 4
