solve for "y" so it is in the form y = mx + b.   "m" is the slope and "b" is the y-intercept.
ax + by = c
       by = -ax + c          <em>subtracted "ax" from both sides</em>
        y  = (-a/b)x  + c/b     <em>divided both sides by "b"</em>
Answer: slope is -a/b    and y-intercept is c/b

Answer:
(8,-3)
Step-by-step explanation:
I just added 1 to the x value and added 2 to the y value because that was the difference between point A and the midpoint of the segment. 
Hope this helps!
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Since the second equation is fully simplified and we know what x equals, we plug the entire equation of x in for x in the top equation:

Now solve for y.

Now plug y back into the bottom equation and solve for x.
