Question

the table represents the points on the graph of a linear function. Which of the following equations best represents the data in the table?​

Answer 1

9514 1404 393

Answer:

f(x) = 3x +5

Explanation:

The x-values change by 1 from the first line to the second.

The y-values change by -13-(-16) = 3 from the first line to the second.

Then the "rate of change" is ∆y/∆x = 3/1 = 3. This will be the coefficient of x in the equation. The last choice is appropriate:

f(x) = 3x + 5
