Answer:
The y-intercept is (0,1)
Step-by-step explanation:
So, first you need to find the equation! Point slope form is (y-y1)=m(x-x1).
Plug the numbers in and you get (y-7)=3(x-2). Now, the y intercept is where x=0, so plug in zero for x.
y-7=3(0-2)
y-7=3(-2)
y-7= -6.
-6+7= 1, so y=1
The ordered pair is then (0,1). Hope this was useful 🙂
