Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The answer is Choice D because if you find the y-intercept, it turns out to be 6. So if you solve for y in choice D you will get that the equation is y=x+6.
It has all the information that was given to us. It has a slope of one and when you find the y-intercept you will see that it also has the y-intercept as 6.
