what do you think?

k_lynn · Answer

try using this awesome graphing calculator https://www.desmos.com/calculator

k_lynn · Answer

if you take a look at it, and type your equations in, you can see if they have a solution or not.  Its so much easier than having to graph them yourself, and I still understand what my teachers are trying to get at after using it.

k_lynn · Answer

Here is what the two equations look like graphed.  WHat do you think the answer is?

kaylak12345 · Answer

there are two points on hte same line but two different lines

k_lynn · Answer

Well, since the lines do not intersect (meet) anywhere, then there can be no solution to these equations.

kaylak12345 · Answer

ok next question

k_lynn · Answer

ok, but you understand how we got that, right?

kaylak12345 · Answer

yes

k_lynn · Answer

ok, great.  Do you have any more questions you need help with?

kaylak12345 · Answer

3x=-12y+15     X+4y=5 there is onlyone line so does that means infinely or one

kaylak12345 · Answer

i think infinely since there are no points that means all of the poinys equal that solution

k_lynn · Answer

when you use that calculator, and there is one line, that means that the equations are technically the same line.  So they have many solutions.

k_lynn · Answer

yes, you're right/

oops **?

k_lynn · Answer

did you need anymore help @kaylak12345

kaylak12345 · Answer

if there are two points on a line does that mean two solutions?

kaylak12345 · Answer

@k_lynn if there is one point on the same does that mean one solution

k_lynn · Answer

what do you mean? can you post a picture? If its like this, there is one solution |dw:1418689226844:dw|
