The graph is a straight line with a positive slope that passes through the point (1, 3) and (5, 7). Using the slope-intercept form of a line, we have:

y = mx + b

where m is the slope and b is the y-intercept. The slope is:

m = (7 - 3)/(5 - 1) = 1

To find b, we can use either point:

3 = 1(1) + b
b = 2

Therefore, the equation of the line is:

y = x + 2

which is choice B.
