For this case the confidence interval is given by :

Answer:
-5
Step-by-step explanation:
There is different ways to solve methods of elimination but if you wanted to cancel y out you would multiply by the opposite sign....for example
7x + 5y = 19
-5 (2x + y = 19) ---> -10x -5y = 95
this would cancel out your y to solve for x so you can plug it back in and solve! hope this helps!!!
First, start off with the x-axis. -6.5, 1 becomes 6.5, 1. This is because point T is 6.5 to the left of the x-axis line, so our new point would be 6.5 to the right of the x-axis line. Same thing for the y-axis, (6.5, 1) would become (6.5, -1).
