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}
