Answer:
4.
Step-by-step explanation:
First, you have to decide whether the slope is negative or positive. Since the line is going diagonally upward, it is positive.
That means the answer has to be either 3 or 4.
Next, you have to decide whether the y-intercept is negative or positive, on the graph, you can see that it is positive.
Answer choice 4 is the only equation where both the slope and the y-intercept are positive, so it is the answer.
