Question

Write the equation of a line that passes through the point (12, 5) and has a slope of -3
​

Answer 1

y - 5 = -3(x - 12)

General Formulas and Concepts:

Algebra I

Coordinates (x, y)

Point-Slope Form: y - y₁ = m(x - x₁)

• x₁ - x coordinate
• y₁ - y coordinate
• m - slope

Explanation:

Step 1: Define

Point (12, 5)

Slope m = -3

Step 2: Write Function

Plug in variables into the general formula.

1. Substitute [PSF]: y - 5 = -3(x - 12)
