Final answer:
An equation is a mathematical statement showing equality between two expressions. The slope-intercept form and point-slope form are two ways to express the equation of a line. The slope formula is used to calculate the slope of a line given two points. Scientific notation is a way to express very large or very small numbers using powers of 10.
Step-by-step explanation:
Equation: An equation is a mathematical statement that shows that two expressions are equal.
Expression: An expression is a combination of numbers, variables, and operations that can be simplified or evaluated.
Slope-Intercept Form: This is a way to express the equation of a line in the form y = mx + b, where m represents the slope of the line and b represents the y-intercept.
Slope Formula: The slope formula is used to calculate the slope of a line given two points on the line. It is expressed as (y2 - y1) / (x2 - x1).
Scientific Notation: Scientific notation is a way to express very large or very small numbers using powers of 10. It is written as a number multiplied by 10 raised to a power.
Point-Slope Form: This is another way to express the equation of a line, using the coordinates of a given point on the line and the slope of the line.
