let's find the slope of the line :

that is :

• 
  `(y2 - y1)/(x2 - x1)`

taking two points (0 , 4) and (2 , -4)

• 
  `(4 - ( - 4))/(0 - 2)`

• 
  `(8)/( - 2)`

• 
  `- 4`

Slope (m) of the graph = -4

and y - intercept (c) = 4

therefore, the equation will be :

• 
  `y = mx + c`

• 
  `y = - 4x + 4`
