Question

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

Answer 1

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}
