Math Problem Statement
Solution
The question is about the equation .
-
Y-intercept: The equation is in slope-intercept form, , where is the slope, and is the y-intercept. Here, the y-intercept is , which means the line crosses the y-axis at the point .
-
Slope: The slope is . Since it is negative, the line will slope downward from left to right.
Therefore, the answer to the last part:
- The line goes downward from left to right.
Would you like further details on how to graph this line, or have any questions?
Here are some related questions to explore:
- How do you determine the direction of a line based on its slope?
- What does the y-intercept represent in a real-world context?
- How can you find the x-intercept of the equation ?
- How would the graph change if the slope were positive?
- What is the effect of changing the y-intercept in the equation?
Tip: In slope-intercept form, the slope tells you the direction and steepness of the line, while the y-intercept indicates where the line crosses the y-axis.
