The point-slope form is:

So, here, you just plug in values:

It would be + 1 because remember, the '-' sign just means the opposite of, not subtraction in this case. Also, m = slope.
Since tom has twice as much as peter and peter has half as much as Mary this shows that Tom and Mary have the same amount

Peter=$3
Answer:
Dimension
Height =29.01
Breadth=38.70
Step-by-step explanation:
Printed area is =386 and margins as specified.
For printed area let height be x and breadth be y.
x*y=386 ⇒ y = 
Now considering the margins
Height = x+6+6=x+12
Weidth =
+8 +8=
+ 16
Area of poster to be minimised =(x+12)(
+ 16)
Differentiate above area with respect to x and equate to zero to find extrema.
= 16 -
=0
x=17.01
Now plug value of x in height and breadth
Height =29.01
Breadth=38.70
