Question

What is an equation in point-slope form of the line that passes through (–3, –1) and has a slope of 2?

Answer 1

Answer:

y + 1 = 2(x + 3)

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 (-3, -1)

Step 2: Write Function

Substitute variables into general form.

y + 1 = 2(x + 3)
