see explanation for (a) and (b)
Explanation:
#(a)x=2# x = 2 is a vertical line, parallel to the y-axis and passing through all points in the plane with an x-coordinate of 2. To graph it plot 2/3 points with an x-coordinate of 2.
For example : (-2 ,-1), (-2 ,0), (-2 ,2), (-2 ,4) and draw a straight line through them.
graph{y-1000x+2000=0 [-10, 10, -5, 5]}
#(b)y=-4# y = - 4 is a horizontal line, parallel to the x-axis snd passing through all points in the plane with a y-coordinate of - 4. To graph plot some points with a y-coordinate of - 4 and draw a straight line through them.
graph{y-0.001x+4=0 [-10, 10, -5, 5]}
