In two or more complete sentences, describe how to graph each of the following equations. in your description, include the slope and both the x- and y-intercepts of each line. 1.y=2. 2.y=-1/2x. 3.x-y=4. 4.x=-1

1. y = 2this is a horizontal line
    y int = (0,2)no x int because it never crosses the x axis
    slope for a horizontal line = 0
     So start at (0,2)...draw ur line straight across (horizontal)...y will always be     2 no matter what x is.

2. y = -1/2x
    y int = (0,0)x int = (0,0)slope = -1/2
    so,basically,start at (0,0)go down one space,and to the right 2 spaces,       then down 1, and to the right 2...keep doing this and u will see ur line. And     if u need more pointssub in any number for x in ur equation, and solve      for y

3. x - y = 4y = x - 4
    y int = (0,-4)x int = (4,0)slope = 1
    start at (0,-4)and since slope is 1, go up 1, and to the right 1, repeatu     should cross the x axis at (4,0)

4. x = -1this is a vertical line
     no y axis because it never crosses y axisx axis = (-1,0)
     slope of a vertical line is undefined. So start at (-1,0), and ur line will be straight up and downx will always be -1, no matter what y is.
    

The first one is 2/3the second is 1/160the third is 4/125
