How do you plot the point R(-3,0)?

1 Answer

See below:

Explanation:

When plotting a point, the numbers in the brackets follow the following pattern:

#(x,y)#

and so the first number is the value of the #x# axis and the second value is the #y# axis. In this case, we can start at the origin, move 3 points to the left along the #x# axis to #-3#, and then, since the #y# value is 0, we don't need to move any further (had it been, for example, 2, we'd move up 2 parallel to the #y# axis.

I'll show you both on two separate graphs.

Here's #(-3,0)#

graph{(x+3)^2+(y+0)^2-.1=0}

And here's #(-3,2)#

graph{(x+3)^2+(y-2)^2-.1=0}
