I expect you intended that to be    y=-7x+2

 

The gradient is -7

so

than angle is


atan(-7) = -81.87degrees   =   108-81.87  

 

108-81.87 = 26.13  degrees

 

If you want me to explain this better I will but only if you request it :/

 

 (plus I have to see your request - if you were a member your could message me the address of the post )
