Question

How do you use the x and y intercepts to graph a linear equation?

Answer 1

If you know the x intercept, you should have a coordinate.
(x-value,0) If you know the y intercept, you should have another coordinate. (0,y-value)

Explanation:

Plot the points on the graph starting right or left with the x value and then up or down with the y-value, finding where they intersect and placing a point. You should have 2 points when you are done. Connect them using a ruler or straight edge and you have graphed a line. graph{y=1/2x+2 [-10, 10, -5, 5]}

Looking at this graph, you will see that the x intercept is -4,0 and the y intercept is 0,2
