Answer:
See the picture attached. The purple line is y=3x+6 and the red line is y=3x+1.
Explanation:
When graphing lines, start with the y-intercept and then use the slope to plot points to help you draw the line.
The equations are in y=mx+b form, where mx is the slope and b is the y-intercept. To get the points, plug in a number where x is. Whatever result you get is the y coordinate for that number.
For example, on the graph in the picture 3(1)+1 = 4. Using that, you would plot the point (1,7).
Hope that makes sense!
