Question

Draw the straight line y = x + 2

Answer 1

Answer:

Using a table work out the values of y

 

  x       −1       0       1  

  y = x       −1       0       1  

(b) The coordinates of the above are (−1, −1) (0, 0) and (1, 1)

(c) Plot the above coordinates and draw a line through these points

   

Example 2.   Plot the graph y = x + 2

(a) Using a table work out the values of y

 

  x       −1       0       1  

  y = x + 2         1       2       3  

(b) The coordinates of the above are (−1, 1) (0, 2) and (1, 3)

(c) Plot the above coordinates and draw a line through these points

   

Example 3.   Plot the graph y = 2x + 3

(a) Using a table work out the values of y

 

x −1    0    1

2x −2    0    2

+3 +3 +3 +3

y = 2x + 3    1    3    5

(b) The coordinates of the above are (−1, 1) (0, 3) and (1, 5)

(c) Plot the above coordinates and draw a line through these points

Answer 2

Answer:

Graph is attached below

Step-by-step explanation:

You first need to plot any two points on the coordinate plane(you can also do more than two points to make it more accurate). Then, using a ruler connect the points and extend the line outwards.
