i don'd understand what you are asking...
You can conclude that X is smaller than Y. For example:
(2,5)
2 + 5 = 7
2 - 5 = -3
Hope this helped!
It is 800 because the 4 can not tell the what to do so that it is
The equation of the tangent line can be found using slope formula and fact that slope = dy/dx.

where (x0,y0) is point A ---> (0,-1)
Then rearrange equation into slope-intercept form:

Finally sub in x=0 into dy/dx to get slope at the point (0,-1)
