Assignment:
Sometimes you need to find the slope of a line based on two given points. Sometimes you need to read a linear equation and determine the slope of a lone from the equation. This solution covers both of these cases and shows how to avoid errors, especially when determining the slope from two points. It also shows how to interpret information from all three forms of the equation of a line.
Provide complete and step by step solution for the question and show calculations and use formulas.
