Asap what is the slope of the line on the graph?

The slope of this line is -1/6.  

2 Point:     (6,2)         (-6,6)
                   x₁ y₁         x₂ y₂
       

Remember: 
  
    rise          change in y          y₂ - y₁          6 - 2            4
  =   = = =
    run            change in x         x₂ - x₁         -6 - 6          -12

Simplify 4/-12

     4 ÷ 4             1
       = = -1/3
   -12 ÷ 4          -3

The slope of the line is -1/3.

Recall that area of the triangle is 1/2*(base)*(height)1/2*(13)*(17) = 110.5the answer is 110.5
