1.) Graph the line using the slope and the y-intercept. please show all work

Make sure to use a straight edge to graph your line. = 2 3 + 6

Slope: ________________ y-intercept: ________________

2.) Calculate the x-intercept and the y-intercept.

Then, graph the line. You must show your work for full credit. Make sure to use a straight edge to graph your line. 2 4 = 8

x-intercept: ________________ y-intercept: ________________
