Answer:
y = -
x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m =
=
= - 
Since the line crosses the y- axis at (0, 6) ⇒ b = 6
y = -
x + 6 ← equation of line
Answer:
2000 feet.
Step-by-step explanation:
Let the length of fence need be x feet.
Then we have the equation:
2lx = 19x + 4000
21x - 19x = 4000
2x = 4000
x = 2000.
You graph it by the y axis and that have a number 1 and you graph it straight sideway
