Graph y=2x-8

Problem

y=2*x−8

Solution

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

2. Determine the y-intercept by looking at the constant term b which is −8 This gives the starting point (0,−8) on the y-axis.

3. Identify the slope m which is 2 This can be written as the fraction 2/1 representing the "rise over run."

4. Plot additional points by starting at (0,−8) and moving up 2 units and right 1 unit to find the next point, (1,−6)

5. Draw a straight line through the points (0,−8) and (1,−6) to complete the graph.

Final Answer

y=2*x−8
