Answer:
y = x + 6
Step-by-step explanation:
y = mx + b
Since (0,6) is your y-intercept (or just positive 6), you have your <em>b</em> part of the equation solved.
The line goes up at a continuous rate of up 1, over 1, so they cancel each other out, making the <em>m </em>part of your equation 1.
So, you have y = 1x + 6 and you change it to just y = x + 6 (since x itself automatically has a 1 before it, when it's by itself).
Hope this helps!
