Introduction
In mathematics, the slope of a line is a fundamental concept that helps us understand the relationship between two variables. It is a measure of how much the line rises (or falls) vertically over a given horizontal distance. In this article, we will focus on finding the slope of a line given by the equation . We will use algebraic techniques to isolate the slope and provide a step-by-step solution.
Understanding the Equation
The given equation is . To find the slope, we need to rewrite the equation in the slope-intercept form, which is , where is the slope and is the y-intercept.
Rearranging the Equation
To isolate the slope, we need to rearrange the equation to make the subject. We can start by adding to both sides of the equation:
Dividing by 10
Next, we divide both sides of the equation by 10 to isolate :
Simplifying the Expression
We can simplify the expression by dividing the numerator and denominator by their greatest common divisor, which is 2:

In our previous article, we discussed how to find the slope of a line given by an equation. However, we know that there are many more questions that you may have about the concept of slope. In this article, we will answer some of the most frequently asked questions about the slope of a line.
Q: What is the slope of a line?
A: The slope of a line is a measure of how much the line rises (or falls) vertically over a given horizontal distance. It is a fundamental concept in mathematics that helps us understand the relationship between two variables.
Q: How do I find the slope of a line?
A: To find the slope of a line, you need to isolate the slope by rearranging the equation to make the subject, simplify the expression, and check your work by plugging in a point on the line to verify that it satisfies the equation.

Q: What is the difference between the slope and the y-intercept?
A: The slope and the y-intercept are two different concepts in mathematics. The slope is a measure of how much the line rises (or falls) vertically over a given horizontal distance, while the y-intercept is the point where the line intersects the y-axis.
Q: How do I determine if a line is parallel or perpendicular to another line?
A: To determine if a line is parallel or perpendicular to another line, you need to compare their slopes. If the slopes are equal, then the lines are parallel. If the slopes are negative reciprocals of each other, then the lines are perpendicular.
Q: Can a line have a slope of zero?
A: Yes, a line can have a slope of zero. This occurs when the line is horizontal, meaning that it does not rise or fall vertically over a given horizontal distance.
Q: Can a line have an undefined slope?
A: Yes, a line can have an undefined slope. This occurs when the line is vertical, meaning that it rises or falls infinitely over a given horizontal distance.
Q: How do I graph a line given its slope and y-intercept?
A: To graph a line given its slope and y-intercept, you need to use the slope-intercept form of a line, which is . You can then plot the y-intercept and use the slope to determine the direction and steepness of the line.
Q: Can a line have a negative slope?
A: Yes, a line can have a negative slope. This occurs when the line falls vertically over a given horizontal distance.
Q: Can a line have a positive slope?
A: Yes, a line can have a positive slope. This occurs when the line rises vertically over a given horizontal distance.
