The equation that best suits the scatter plot is y = x - 0.5.
A straight line graph has the general equation; y = mx + c Where; m = slope, c = y- intercept. We now have to examine each of the equations as written so as to determine which of the equations that best suits the scatter plot as shown.
First of all, we can see that the line did not start from origin. Looking at the graph very closely, we can conclude that the equation that best suits the scatter plot is y = x - 0.5.
