Math Problem Statement
What is the equation of the line passing through the points shown in the graph?
Solution
The graph you provided shows a line passing through two points on a coordinate grid. To analyze the line, I will:
- Identify the coordinates of the two points through which the line passes.
- Calculate the slope using the formula:
- Derive the equation of the line using the slope-intercept form:
where is the slope and is the y-intercept.
Step 1: Identifying the points
From the graph, the two points that the line passes through appear to be approximately:
Step 2: Calculating the slope
The slope is:
Step 3: Equation of the line
Using the slope and the y-intercept , the equation of the line is:
