Question

I want to know if I did this correctly or not.

Graph the linear equation.

x-y=3

This is how I did it below:

1. I plugged "0" in for the x and got the y-value of -3. (0-y=3)

2. I plugged "0" in for the y and got the x-value of 3. (x-0=3)

3. So, with both of those put together I got the ordered pair of (3,-3).

Is this the correct answer to graph for this equation?

Answer 1

No. Although step 1 & 2 are somewhat correct, the last is not (Indeed, you need 2 points to graph a line not one). In 1 and 2, you get a pair (x,y), for y = 0 and x=0 respectively, that is (0,-3), and (3,0). You can then draw a line between these two points.

Answer 2

pretty close, but you should use (x,y) pairs the x you use to find the y go together

Answer 3

Here is a video that shows how to do this, if you want more info

Answer 4

Thanks. So it would be, (0,-3) and the (3,0).

Answer 5

yes, now plot those points and draw a line through them
