Best ResponseYou've already chosen the best response.1Is the "yx=21" and "y=8x" provided in your problem, or is that part of your work to solve it?

Best ResponseYou've already chosen the best response.1Ok, and is it one of the questions that may have multiple answers?

Best ResponseYou've already chosen the best response.1Does your question state that multiple answers could be correct, or is it a standard multiple choice question with only one solution?

Best ResponseYou've already chosen the best response.1Ok, let's ignore the two given slopeintercept formulas for the moment. Does the X and Y coordinate ALONE give us the constant, also known as "k"?

Best ResponseYou've already chosen the best response.1I can see why you'd think that, but unfortunately it does not. If you say yes because the formula for k is k=(y/x), then you might mistakenly put intercepts as your x and y values, but you have to get those variables from solving for x and y, given a specific set of equations, and neither of your given equations fits that bill.

Best ResponseYou've already chosen the best response.1So let's try the next possibility. Does the given intersection point of (3,24) provide us with a yintercept?

Best ResponseYou've already chosen the best response.1Explain how please. In order to help you understand why the right answer is right, I need to know your thought process for this one.

Best ResponseYou've already chosen the best response.0I'm guessing the yintercept is 24 because it's on the yaxis

Best ResponseYou've already chosen the best response.0Is that right ? @noseboy908

Best ResponseYou've already chosen the best response.1It depends how you say that it's on the yaxis. More exactly, the yaxis is used for the ordered pair to simply say how high on the yaxis the point is, but you have to take into account the x value too. Understand?

Best ResponseYou've already chosen the best response.0Wat I mean is so the coordinates are (3,24) so the 3 would be where the xaxix is and the 24 is where the yaxix is but I understand wat ur trying to say

Best ResponseYou've already chosen the best response.1Ok, now let's go to the next possibility. Let's keep it simple. Can you determine slope of a line when all you know about that line is a single point on it?

Best ResponseYou've already chosen the best response.0Did you mean can we find the slope of a line knowing only one of the points ?

Best ResponseYou've already chosen the best response.1Good, I was hoping I'd not have to defend that fact! Now, finally, look at the last possibility for an answer. When we have two lines that intersect at one or more points, what do we call those points?

noseboy908

Best ResponseYou've already chosen the best response.1Correct, but can you think of any other terms?

noseboy908

Best ResponseYou've already chosen the best response.1I'll tell you, as you may have never heard it before. Another term for the intersection of two lines, given the right question, is the "solution", therefore, when you have two or more of them, you can have multiple solutions, but that's getting into higher math. So, what does that leave us for an answer?

Best ResponseYou've already chosen the best response.0Ohhhhh yea I'm sorry I forgot and so the answer would be C. The yintercept

Best ResponseYou've already chosen the best response.1Ok, we just determined that the intersection of two points is called what?

Best ResponseYou've already chosen the best response.1And which answer is that?

noseboy908

Best ResponseYou've already chosen the best response.1Exactly!! Now, be honest with me, do you understand why the other answers are not correct?

Best ResponseYou've already chosen the best response.0Yes .. But can you explain to me why the answer isn't C. Please ?

noseboy908

Best ResponseYou've already chosen the best response.1Of course! Firstly, it's imperative to note that ALL yintercepts have an inherent xvalue of 0. That's because if was any different, then the point would actually fall x units right or left of the axis!
