Math Problem Statement
Solution
To find the equation of the line, we need to determine two components:
-
The slope (): The slope is calculated as: From the graph, the line rises from to , and runs from to . Therefore: So:
-
The y-intercept (): This is the -value where the line crosses the -axis. From the graph, the line crosses the -axis at .
The equation of the line in slope-intercept form is:
