Find the equation of the line that is parallel to the line x+3y=-15 that passes through the origin

Monica [59]

You would subtract x from each side. It would then be 3y=-x-15. Then you would divide all of the equation by 3. Your final answer would be y=-3x-5.

KIM [24]

Answer:

y - 1 = 2(x - 2)

General Formulas and Concepts:

Algebra I

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate
y₁ - y coordinate
m - slope

Step-by-step explanation:

Step 1: Define

Slope m = 2

Point (2, 1)

Step 2: Write Equation

Substitute in variables: y - 1 = 2(x - 2)
