The value of X is 39 degrees. You have to add 102 degrees and 39 degrees to get 141 degrees. All triangles equal up to 180, so subtract 141 from 180, and you get 39 degrees.
Answer = slope -1/2 intercept 1
Using the rise/run method, you can see that the slope is -1/2 (It’s negative because if the line wen the other way, it would be positive)
As for the y-intercept, the line intercepts the line at 1, so the y-intercept is +1.
Hope this helps :)
The square roots for all of the answers would be rooted 2 squared time whatever number you picked for the first part
