Math Problem Statement
Graph the equation y = 2x - 5 using the provided grid.
Solution
The equation given is . Let me explain how to graph this step-by-step:
-
Identify the slope and y-intercept:
- The equation is in slope-intercept form , where is the slope and is the y-intercept.
- Here, (the slope) and (the y-intercept).
-
Plot the y-intercept:
- Start by plotting the point where on the y-axis. This point is .
-
Use the slope to find another point:
- The slope means "rise over run" = . From the point , move up 2 units (rise) and right 1 unit (run), landing at . Plot this point.
-
Extend the line:
- Using a ruler, draw a straight line passing through both points, extending it in both directions. Ensure the line follows the slope pattern (e.g., continuing up 2 and right 1, or down 2 and left 1).
-
Label the line:
- Add the equation near the line to identify it.
