Math Problem Statement
A line passes through the point (-8, 5) and has a slope of -3/4
Write an equation in point-slope form for this line.
Solution
To write the equation of a line in point-slope form, we use the formula:
where:
- is a point on the line,
- is the slope of the line.
Given:
- The point ,
- The slope ,
Substituting these values into the point-slope form:
This is the equation of the line in point-slope form.
Would you like to go into more detail about how to convert this into slope-intercept form or explore a related topic?
Here are five questions related to this concept:
- How do you convert the point-slope form to the slope-intercept form?
- What is the slope-intercept form of the equation derived above?
- How do you find the equation of a line parallel to this line?
- What is the y-intercept of the line described by this equation?
- How can you determine the x-intercept of this line?
Tip: The point-slope form is particularly useful when you know a point on the line and the slope, as it directly incorporates this information into the equation.
