Question
For the linear function h, the table above shows several values of x and their corresponding values of h(x). Which of the following defines h?
- h(x) = 2x - 3
- h(x) = 3x - 5
- h(x) = 4x - 7
- h(x) = 4x - 9
The correct answer is: h(x) = 3x - 5
The linear equation from two points is 
The points here are (2, 1) & (4, 7)
y - 1 = 3(x - 2)
y = 3x - 6 + 1 = 3x - 5
h(x) = 3x - 5
