Math Problem Statement
find line equation
Solution
The image you've provided shows a straight line on a graph. To determine the equation of the line, I will analyze the slope and y-intercept based on the graph. Let's go through the process:
Steps:
-
Identify two points on the line: It looks like there's a clear point at and another one near .
-
Find the slope (m): The slope is calculated by the formula: Using the points and :
-
Use the point-slope form to find the equation: Now that we know the slope, we can use the point-slope form of a line's equation: Using the point and : Simplifying this equation:
Final Equation:
The equation of the line is:
