Can anyone tell me what A stands for? Sorry this is only my second day of geometry.
jimthompson5910 (jim_thompson5910):
A just a point, or the name of the point
jimthompson5910 (jim_thompson5910):
You can call it anything you want, the name A has no meaning or significance
jimthompson5910 (jim_thompson5910):
If you want, you can erase the "A" to get (1,0) and you'd still have the same question.
jimthompson5910 (jim_thompson5910):
So is the point (1,0) on the line y = x+1?

I guess?? I think thats what it's asking
jimthompson5910 (jim_thompson5910):
y = x+1
0 = 1+1 ... Plug in (1,0), basically x = 1 and y = 0
0 = 2
Since that equation is false, (1,0) is NOT a solution
So (1,0) is NOT on the line
OpenStudy (anonymous):
So you plugged in 1 for y and 0 for x?
jimthompson5910 (jim_thompson5910):
1 for x
jimthompson5910 (jim_thompson5910):
0 for y

So the first number in the parenthesis will always be x and the second will be y?
jimthompson5910 (jim_thompson5910):
yes
jimthompson5910 (jim_thompson5910):
(x,y) is any point
OpenStudy (anonymous):
okay thanks soooo much just to be certain after you plugged everything in it would be like 0=2 and thats why it's no?
jimthompson5910 (jim_thompson5910):
yes that's exactly why
