To find the equation of the bue line, first find the y-intercept. The y-intercept for this line is 3. Then you can use the rise over run method by finding the nearest point that the line connects to and find that the point is 2 units above and 1 unit to the right of the y-intercept. 2/1 = 2 so the slope is 2. From this information, we can find that the equation for the line is y = 2x + 3.
