Answer:
y = x + 1
See below.
Step-by-step explanation:
To find the slope intercept form of a line, calculate the slope first.

So the slope is 1. Substitute m = 1 and (1,2) into the point slope form. Then simplify to slope intercept form.
y - 2 = 1 (x - 1)
y - 2 = x - 1
y = x + 1
The answer to the question above is the third choice, "a shelf on a wall". The shelf is usually made of rectangular pieces of materials that are then connected to each other to form quadrilaterals. The sides of the shelf are planes.
