Math Problem Statement

Drag the red and blue dots along the x-axis and y-axis to graph minus, x, plus, y, equals, 5

Solution

To graph the equation x+y=5-x + y = 5, you can rearrange it into slope-intercept form y=mx+by = mx + b. This gives:

y=x+5y = x + 5

Steps to graph:

  1. Find the y-intercept: Set x=0x = 0: y=0+5=5y = 0 + 5 = 5 So the point is (0,5)(0, 5).

  2. Find the x-intercept: Set y=0y = 0: 0=x+5    x=50 = x + 5 \implies x = -5 So the point is (5,0)(-5, 0).

  3. Plot the points: Plot (0,5)(0, 5) and (5,0)(-5, 0) on the graph.

  4. Draw the line: Connect these points with a straight line, extending it in both directions.

If you have graphing software or a physical graph, you can drag the dots at (0,5)(0, 5) and (5,0)(-5, 0) to visualize the line.

Tip: Always check your intercepts; they are crucial for accurately drawing linear graphs.
