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 written as y=m*x+b

2. Determine the slope m and the y-intercept b In the equation y=x+3 the slope m is 1 and the y-intercept b is 3

3. Plot the y-intercept on the coordinate plane. This is the point (0,3)

4. Use the slope to find a second point. Since the slope m=1 (or 1/1, move up 1 unit and right 1 unit from the y-intercept (0,3) to reach the point (1,4)

5. Draw a straight line passing through the points (0,3) and (1,4) to complete the graph.

Final Answer

y=x+3
