Explanation:

The value of #y# is the result of assigning a value to #x#, multiplying that value by 4. The answer is 'what #y# is worth'.

#"Point"_1" For "x=2;" " y=4xx2" "=" "8#

#"Point"_2" For "x=6;" "y=4xx 6" "=" "24#

#"Point"_3" For "x=0;" "y= 4 xx 0" " =" "0#

Consider point 1

Find on the x-axis the value of +2. Draw a very light line vertically.
Look along the y-axis until you find the point +8. Draw a very light line horizontally. Where the two lines meet is the point.

Repeat this process for one other value. Draw a line through the two points and that is your graph.

Important: Label your axis and put a title on your graph. You could right 'The graph of y=4x' This action will get you extra marks.

Your graph should look something like this
