Horizontal Line Test. lessons in math, English, science, history, and more. The equation for the basement example given above would be, y=-1. Since the height of a horizontal line is always the same, regardless to the x-value of a point on the line, the horizontal line has the equation, y=A number, where the number is simply the height or y-value of the line. Graph the horizontal line y = - 2. Here’s what is looks like in it’s simplest form. The horizontal line may reference some target value or limit, and adding the horizontal line makes it easy to see where values are above and below this reference value. succeed. - Definition & Examples, Figure of Speech: Definition, Types & Examples, The Differences Between Inductive and Deductive Reasoning, Singular & Plural Nouns: Definitions, Rules & Examples, GED Math: Quantitative, Arithmetic & Algebraic Problem Solving, McDougal Littell Algebra 2: Online Textbook Help, Common Core Math - Number & Quantity: High School Standards, Common Core Math - Algebra: High School Standards, Common Core Math - Statistics & Probability: High School Standards, SAT Subject Test Mathematics Level 1: Practice and Study Guide, SAT Subject Test Mathematics Level 2: Practice and Study Guide, Introduction to Statistics: Help and Review, Introduction to Statistics: Tutoring Solution, AP Calculus AB & BC: Homework Help Resource. 1.
