You can put this solution on YOUR website! This is not hard, once I show you, you should be able to do it forever!
graph y = x - 3
:
Choose at least two values for x and find y,
x = -4
y = (-4) - 3
y = -2 - 3
y = -5
plot the pair: -4, -5
and
x = +4
y = (4) - 3
y = 2 - 3
y = -1
plot the pair: 4, -1
:
A third easy pair to find is x=0
y = (0) - 3
y = -3
:
Join these two points, your graph should look like this:
:
:
How about this? Can to graph simple equations like this now? Sometimes you
have to try various values of x, to bring the graph in range of the graphing
device that you are using. C
