Graphing straight lines question?

Simply assign any value for x or y and solve for the other.

Do that twice and the line passing through both points is the graph of that line.

y = x + 1

zeros are pretty easy to work with.

If x = 0

y = 0 + 1

y = 1

.................. x = 0, and y = 1 ...... first point is at (0,1)

If y = 0

0 = x + 1

x = -1

................. x = -1, and y = 0 ...... second point is at (-1, 0)

Draw a line passing through both (0, 1) and ( -1, 0)

The easiest way is:

First of all set y = 0 : this gives points (-1,0 : 2,0 : and -2,0)

The let x = 0 : this gives points (0,1 : 0, -2 : and 0,2)

Then draw the lines between the respective points and extend it. I chose x=0 and y = 0 because these points are on the y axis and x axis respectively.
