Answer:

Explanation:
As you can see the graph is going upwards, it means it has a positive slope. If we observe the general form of straight line:

m is the slope of the line and coefficient of x in this equation. So if slope is positive, then coefficient of x should be positive as well.
As the only one among the options with a positive coefficient of x (positive sign of slope) is
, the better line trend will y = x + 6 (ans)
Extra point:
As u can notice the line starts from a certain point in y-axis rather than original, this point is known as y-intercept or c in the equation. As it is also positive, y = x + 6 is the best possible answer for this trend.
