Answer:
To show the equation x - 4 = 1 on a number line, we can follow these steps:
1. Start by marking the number 4 on the number line.
----|----|----|----|----|----|----|----|----|----|
-4 -3 -2 -1 0 1 2 3 4 5
2. Since the equation is x - 4 = 1, we need to find the value of x that satisfies this equation. To isolate x, we can add 4 to both sides of the equation:
x - 4 + 4 = 1 + 4
x = 5
3. Now, mark the number 5 on the number line to represent the value of x:
----|----|----|----|----|----|----|----|----|----|
-4 -3 -2 -1 0 1 2 3 4 5
4. Finally, draw a line or arrow connecting the numbers 4 and 5 to indicate the solution to the equation x - 4 = 1:
----|----|----|----|----|----|----|----|----|----|
-4 -3 -2 -1 0 1 2 3 4 5
↑
x=5
So, on the number line, the solution to the equation x - 4 = 1 is represented by the point x = 5.
