Solution
Let’s analyze the questions in the image and find the slopes for the given equations:
Question 17:
The equation is .
- The equation is in slope-intercept form: , where is the slope and is the y-intercept.
- Here, .
Answer: The slope is .
Question 18:
The equation is .
- Again, this is in slope-intercept form .
- Here, , as the coefficient of is .
Answer: The slope is .
Would you like a detailed explanation of the slope-intercept form or further clarification?
Here are 5 related questions to deepen your understanding:
- How can you determine the slope of a line if the equation is not in slope-intercept form?
- What is the slope of a vertical line, and why is it undefined?
- How does the slope of a line relate to its steepness and direction?
- Can you write the equation of a line if the slope and a point are given?
- What does the slope represent in real-world applications, such as in physics or economics?
Tip: To quickly identify the slope, always rewrite the equation in form, if it’s not already.
