What is the length of the figure?
1 answer:
There are two ways to do this. One is by adding up the squares, which takes a while. The other way is if you notice that the length along the bottom is the same as that long the top, and the same is true for the sides. While it does not appear this way at first, imagine that that was the floor plan of a house. If you looked at it from the side, you wouldn't see the dent in the corner, only one side. Since the length of the top is 13 units, from -7 to 6, and the side is also 13 units, from -6 to 7, the answer is 
52 units long.
52 units long.

An equation in slope-intercept form of the line
Given :
Bill began his diet when he weighed 268 pounds.
After 4 weeks he weighed 250 pounds
Lets 'w' represents weeks and 'p' represents pounds
Using the given information ,we find two points (w,p)
Bill began his diet when he weighed 268 pounds.
when w=0 , weight in pounds =268
(0,268)
After 4 weeks he weighed 250 pounds, so point is (4,250)
Use two points to write the equation of line
Slope intercept form is y=mx+b
where m is the slope and b is the y intercept
slope formula using 2 points (0,268) and (4,250)
now use slope m and any one point (0,268) to write equation
we know that w represents weeks and p represents pounds
The equation of the line in slope intercept form is
