Graph y=x-3

Problem

y=x−3

Solution

1. Identify the type of equation. This is a linear equation in slope-intercept form, which is y=m*x+b

2. Determine the slope m and the y-intercept b In this equation, m=1 and b=−3

3. Plot the y-intercept. The point (0,−3) is where the line crosses the y-axis.

4. Use the slope to find a second point. Since the slope is 1 or 1/1 move up 1 unit and right 1 unit from (0,−3) to reach the point (1,−2)

5. Draw a straight line passing through the points (0,−3) and (1,−2) to complete the graph.

Final Answer

y=x−3
