Write the equation in point slope form for a line that passes through the points (-2,3) and (6,-1)

diamong [38]

Answer:

y - 3 = -1/2(x + 2)

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate

y₁ - y coordinate

m - slope

Step-by-step explanation:

Step 1: Define

Point (-2, 3)

Point (6, -1)

Step 2: Find slope m

Substitute: $m=\frac{-1-3}{6+2}$
Subtract/Add: $m=\frac{-4}{8}$
Simplify: $m=\frac{-1}{2}$

Step 3: Write linear equation

Point-Slope Form: y - 3 = -1/2(x + 2)
