Answer:
-4/5
-0.8
Step-by-step explanation:
To find the length of line AB, use the midpoint formula and solve for AB.
To find the length of line AB, we can use the midpoint formula. Given that point T is the midpoint of line AB, we can set up the equation:
(AT + TB) / 2 = AB
Substituting the given values:
((3/4)x + 6 + (1/2)x + 9) / 2 = AB
Simplifying the equation:
(5/4)x + 15 / 2 = AB
(5/4)x + 7.5 = AB
Therefore, the length of line AB is (5/4)x + 7.5.
