Question 591583
a graph of the equation of y = 2x-3 is shown below:
{{{graph(600,600,-5,5,-15,15,2x-3)}}}
your table will look like this:
<pre>
x             y = 2x-3
-3              -9
-2              -7
-1              -5
 0              -3
 1              -1
 2               1
 3               3
</pre>
all you're doing is replace x in the equation of y = 2x-3 with the value of x.
when x = -3, y = 2x-3 becomes y = 2(-3) - 3 which becomes y = -6 - 3 which becomes y = -9
similarly, when x = 3, y = 2x-3 becomes y = 2(3) - 3 which becomes y = 6 - 3 which becomes y = 3.
etc.
