Use the point and the slope to graph each line. Write the equation of the line. The line passes through point (-1,-4) and has slope -2

y + 4 = -2(x + 1)

General Formulas and Concepts:

Algebra I

Coordinate Planes

Point-Slope Form: y - y₁ = m(x - x₁)

Step-by-step explanation:

Step 1: Define

Identify variables

Point (-1, -4)

Slope m = -2

Step 2: Find Equation

Step 3: Graph
