Math Problem Statement
Solution
The image shows a graph of a straight line. To find the equation of the line, we need to identify its slope and y-intercept. Let's analyze this step by step:
1. Identifying Points
We can see two clear points on the line:
- The point
- The point , which is the y-intercept.
2. Slope Calculation
The formula for the slope of a line passing through two points and is: Using the points and :
3. Equation of the Line
The slope-intercept form of a line is: where is the slope and is the y-intercept. From the graph, the y-intercept is .
Thus, the equation of the line is:

Here are some related questions to expand your understanding:
- How do you find the equation of a line if you only have one point and the slope?
- What is the relationship between the slope and the steepness of the line?
- How can you rewrite the equation in standard form ?
- What happens to the graph if the slope becomes positive?
- How can you find the x-intercept from the equation of the line?
Tip: Remember, the slope tells you how much changes for each unit of change in , which helps you visualize the steepness and direction of the line.
