Find the slope of the tangent line to the curve y= 4 / 3(x^3 - 2x^2 + 3x -5) at (2, 4/3)

the answer choices are
1) 2/3
2) 4/3
3) -28/3
4) -8/3
5) 8/3

My answer was 4/3 but this is wrong.
Answered by Reiny
dy/dx = (4/3)(3x^2 - 4x + 3)
when x = 2
dy/dx = (4/3)(12 - 8+3 = (4/3)(7) = 28/3
Answered by Hannah
is it negative 28/3?
Answered by Reiny
check my steps, perhaps I am not seeing something
I get +28/3

No they look right I guess they messed up on the answer choices
