Drawing Straight Line Graphs

We will look at plotting various straight line graphs in the applets below.
[size=200]1) y = x + 1[/size]
a) For the graph of y = x + 1 where -5 ≤ x ≤ 5
List all of the coordinates on this line with integer (whole number) x values[br][br]e.g. (0,1)
b) Draw the graph of y = x+1 for -5 ≤ x ≤ 5
[size=200]2) y = 2x + 1[/size]
a) For the graph of y = 2x + 1 where -4 ≤ x ≤ 2
List all of the coordinates on this line with integer (whole number) x values[br][br]e.g. (0,1)
b) Draw the graph of y = 2x+1 for -4 ≤ x ≤ 2
[size=200]3) y = -2x + 1[/size]
a) For the graph of y = -2x + 1 where -3 ≤ x ≤ 4
List all of the coordinates on this line with integer (whole number) x values[br][br]e.g. (0,1)
b) Draw the graph of y = -2x + 1 for -3 ≤ x ≤ 4
[size=200]4) y = -x - 1[/size]
a) For the graph of y = -x - 1 where -5 ≤ x ≤ 5
List all of the coordinates on this line with integer (whole number) x values[br][br]e.g. (0,1)
b) Draw the graph of y = -x - 1 for -5 ≤ x ≤ 5
[size=200]5) y = x + 2 and y = 2x - 2[/size]
a) Plot the graphs of y = x + 2 and y = 2x - 2. Label each line.
b) Can you see any values where x + 2 = 2x - 2? If so, where?
