Answer: The second graph.

Step-by-step explanation: If you look at the equation you will see that the y-intercept will be -2. You can also see that there is a (4x) and when you see that think of (x) as 1. So, you will move up 4 and over 1 to the right. The opposite would be down 4 and over 1 to the left

Answer:

The second graph represents the equation f(x) = 4x - 2.

Explanation:

Given that the equation for a linear function is f(x) = mx+b, m being the slope and b the y intercept,

The y-intercept (-2) matches the same one from graph 1 and 2.

However, With the slope being 4, only the 2nd graph works, since graph one's slope is 1/4.

The answer is: The second graph represents the equation f(x) = 4x - 2.
