Please answer if you actually know!! LINEAR FUNCTION

This is a linear function because x is decreasing at a constant rate and y is increasing at a constant rate. You can also prove this by graphing each point- you will see that it makes a straight line.

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

answer:

f(5/2) = 10/3

i hope this you!
