Answer:
The correct answer is:
y = 2x + 3
Step-by-step explanation:
Step-by-step explanation:
The slope of the line is 2, and the y-intercept is 3. This means that the function is in the form of y = mx + b, where m is the slope and b is the y-intercept. Therefore, the function that can best be represented by the graph is y = 2x + 3.
Here are some examples of how to use the function:
To find the y-value for x = 1, we can substitute 1 into the function: y = 2(1) + 3 = 5
To find the x-value for y = -1, we can set y equal to -1 and solve for x: -1 = 2x + 3, -4 = 2x, x = -2
We can also use the function to graph other points on the line. For example, to graph the point (2, 7), we can substitute 2 into the function to find the y-value: y = 2(2) + 3 = 7. We then plot the point (2, 7) on the graph.
