Math Problem Statement
Solution
The problem asks to determine which system of equations corresponds to the graph provided. Let's analyze it step-by-step.
-
Identifying the lines: The graph shows two intersecting lines. Let's find the equations for each line by examining their slopes and y-intercepts.
-
First line: It passes through points and . The slope is given by: The equation of the line in slope-intercept form is: Multiply by 3 to eliminate the fraction:
-
Second line: It passes through points and . The slope is: The equation of this line is: Multiply by 3 to eliminate the fraction:
-
-
Matching with given options: We now compare the simplified forms of the equations:
- First line:
- Second line:
None of the equations in the answer choices are presented exactly like this, but they could be manipulated. Looking at the choices closely, let's check option D:
- (manipulate ) might correspond to a transformation in slope direction.
