The length of the bigger piece is 17 meters and the entire length is 29 meters
Answer: 
Step-by-step explanation:
The point-slope form of the equation of the line is:

Where "m" is the slope of the line and
is a point of the line.
You know the value of the slope and you also know a point of the line, then you need to substitute values into
.
Therefore, you get that the equation of this line in point-slope form is:

Y = mx + b
slope(m) = -4
(-2,5)....x = -2 and y = 5
now we sub into the formula and find b, the y int
5 = -4(-2) + b
5 = 8 + b
5 - 8 = b
-3 = b
so ur equation is : y = -4x - 3 <==
