Solution

The equation of a line in slope-intercept form is given by y = mx + c, where m is the slope and c is the y-intercept.

Given that the line passes through the point (2, 1) and has a slope m = 2, we can substitute these values into the equation to find the y-intercept c.

1 = 2*2 + c 1 = 4 + c c = 1 - 4 c = -3

Therefore, the equation of the line is y = 2x - 3.

So, the correct answer is D. y = 2x - 3.
