Formula for distance between two points:
d = √( (x₂ -x₁)² + (y₂ - y₁)²)
x₁ = -2, y₁ = 4, x₂ = 0, y₂ = -6
d = √( (x₂ -x₁)² + (y₂ - y₁)²)
d = √( (0 - -2)² + (-6 - 4)²)
d = √( (0 + 2)² + (-10)²)
d = √( (2)² + (-10)²)
d = √(4 + 100)
d = √104 Use a calculator
d ≈ 10.1980
d ≈ 10.20 units to the nearest hundredth.
Answer:
Are we supposed to put numbers there?

I am still gonna try to help you out, ok?
System of Linear Equations entered :
[1] y - 2x/3 = -1
[2] y + x = 4
// To remove fractions, multiply equations by their respective LCD
Multiply equation [1] by 3
// Equations now take the shape:
[1] 3y - 2x = -3
[2] y + x = 4
Graphic Representation of the Equations :
-2x + 3y = -3 x + y = 4
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -y + 4
// Plug this in for variable x in equation [1]
[1] 3y - 2•(-y +4) = -3
[1] 5y = 5
// Solve equation [1] for the variable y
[1] 5y = 5
[1] y = 1
// By now we know this much :
y = 1
x = -y+4
// Use the y value to solve for x
x = -(1)+4 = 3
I hope this help you
First calculate th feet of lace she haven't used.
9 - 3 = 6 ft
now we can convert feet into yard. we can divide the amount into 3 because it says 3ft is 1yrd
6 / 3 = 2 yards
