It's 66

Explanation:

You don't even need to remember any formula: the yy-intercept is, quite intuitively, the point in which the line crosses the yy-axis. But the point of that axis are the ones with xx-coordinate equal to zero. So, you need to find the value of the function when evaluated for x=0x=0. In this case, y(0)=2*0 + 6 = 6y(0)=20+6=6.
