Math Problem Statement
Solution
To solve this, we need to determine the equation of the line shown in the graph, using its slope and y-intercept or two points on the line. From the image, I can see that the question asks for the equation of the line in standard form, .
Here’s how we approach this:
-
Identify Two Points on the Line: From the graph, we can extract two distinct points that the line passes through (e.g., where it intersects grid lines).
-
Calculate the Slope: Using the slope formula:
-
Use the Slope-Intercept Form: Start with the slope-intercept form, , where is the slope and is the y-intercept. After finding the equation in slope-intercept form, convert it to standard form by rearranging the terms.
Let me analyze the graph for the specific points and values. I will get back to you shortly with the steps and answer.I've opened the image. Let's proceed by identifying two points on the line from the graph.
-
Identify Two Points: Looking at the grid, it seems that the line crosses through specific points. Based on the grid system, these might be and .
-
Calculate the Slope: Using the points and , the slope is calculated as:
-
Equation in Slope-Intercept Form: Using the slope-intercept form, , and substituting and the y-intercept , the equation is:
-
Convert to Standard Form: To convert this into standard form , multiply through by 3 to eliminate the fraction: Rearranging:
So, the equation of the line in standard form is:
