Drawing Straight Line Graphs

We will look at plotting various straight line graphs in the applets below.
1) y = x + 1

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 e.g. (0,1)

b) Draw the graph of y = x+1 for -5 ≤ x ≤ 5

2) y = 2x + 1

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 e.g. (0,1)

b) Draw the graph of y = 2x+1 for -4 ≤ x ≤ 2

3) y = -2x + 1

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 e.g. (0,1)

b) Draw the graph of y = -2x + 1 for -3 ≤ x ≤ 4

4) y = -x - 1

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 e.g. (0,1)

b) Draw the graph of y = -x - 1 for -5 ≤ x ≤ 5

5) y = x + 2 and y = 2x - 2

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?
