How to answer straight line graph questions in the GCSE exam?
Example 1:
(a) Complete the table of values for y = 2x + 5
(b) On the grid, draw the graph of y = 2x + 5 for the values from x = -2 to x = 2
Example 2:
(a) Complete the table of values for y = 2x - 3
(b) On the grid, draw the graph of y = 2x - 3
(c) Use your graph to find
(i) the value of y when x = -1.5
(ii) the value of x when y = 6
Example 3:
On the grid, draw the graph of y = 3x - 2 for the values of x from -1 to 3
Example 4:
On the grid, draw the graph of y = 3 - 2x for the values of x from -2 to 4
Example 5:
On the grid, draw the graph of y = 1/2 x + 3 for the values of x from -2 to 4
