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
1) P=2w +2l
46=2w +14
32=2w
16= w or width
2) A=lw
A=7 x 12
A= 84
3) A= 12 x 21
A= 252
