Tonya and Pearl each completed a separate proof to show that alterate interior angles AKL and FLK are congruent. Who completed the proof incorrectly? Explain

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

2+2 obliviously is 4.
