Question 970410
Coordinate for horizontal axis is x.
Coordinate for vertical axis is y.
Two dimensional ordered pair coordinates are indicated in a form, (x,y).


The equation is shown as y in terms of x.  Beginners can make a table of x & y values to identify (x,y) points and then plot them on graph paper.


Pick x________|_________Find y
____-2________|_______8(-2)-2=-18
____-1________|_______8(-1)-2=-10
______0_______|________8*0-2=-2
_____3________|_______8*3-2=22
_____4________|_______8*4-2=30


The corresponding points to be plotted for making a graph are:
(-2,-18), (-1,-10), (0,-2), (3, 22), (4,30).



A graph should be consistant with this, and contains whatever points you found:'
Axes are different scale sizes:
{{{graph(300,300,-4,6,-20,30,8x-2)}}}


A close-up using same scale size for each axis:
{{{graph(300,300,-4,6,-4,6,8x-2)}}}
