Graph y=3x-8

Problem

y=3*x−8

Solution

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

2. Determine the y-intercept from the constant term b=−8 which gives the point (0,−8)

3. Identify the slope m=3 which represents the ratio of vertical change to horizontal change, or rise/run=3/1

4. Plot the y-intercept at (0,−8) on the coordinate plane.

5. Use the slope to find a second point by moving up 3 units and right 1 unit from (0,−8) to reach (1,−5)

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

Final Answer

y=3*x−8
