Step-by-step explanation:
All you do is multiply 22 times 8 which is 176 then you multiply 8*4
To find the slope of two points you use the formula: 
In this case we can assume that:
= -20



Plug the above into the equation I gave you at the start and solve:


Now reduce:
÷2

^^^Slope for these two points
Hope this helped!
