y=x/2+k
y-intercept 3 means (0,3) is a point on the line
Using (0,3): 3 = k;
y=x/2+3 => 2y-x = 6;
You made a slight mistake

The slope-intercept form of a line is given by , where m = slope of the line and b = y-intercept. Thus the equation of the line, by direct substitution, is . Multiplying both sides by 2 we get 2y = x +6
