Introduction:
Unlock the power of figures of speech! In this comprehensive guide for Grade 9 students, we explore similes, metaphors, hyperboles, personification, alliteration, onomatopoeia, and irony. Discover how these expressive tools can transform your writing, captivating readers with vivid imagery and engaging expressions.
Simile:
Similes
compare two different things using "like" or "as."
For example,
"Her laughter was contagious, like a child's joyful giggle."
Here, the writer compares the contagiousness of her laughter to the contagiousness of a child's giggle.
How to Find the Equation of a Perpendicular Line: Step-by-Step Guide
1. Determine the Slope of the Given Line: To begin, identify the slope \((m)\) of the given line. 
2. Calculate the Negative Reciprocal of the Slope: Find the negative reciprocal of the slope, denoted as \(\frac{-1}{m}\). This value represents the slope of the perpendicular line.
3. Identify a Point on the Perpendicular Line: Select a point that lies on the perpendicular line.
You can either use a provided point or choose a convenient one.
4. Use the Point-Slope Form to Write the Equation: Utilize the point-slope form of a line, which is y - y1 = m(x - x1).
Substitute the negative reciprocal of the slope \((\frac{-1}{m})\) for m and the coordinates of the point (x1, y1) into the equation.
