Best ResponseYou've already chosen the best response.1If were using point slope form(PSF) then were going to substitute the values of the ordered pairs into our equation. So knowing that our ordered pairs go in the order (x,y) *alphabetical order* then what values would we substitute in for y sub one and x sub one.

Best ResponseYou've already chosen the best response.1Well were trying to isolate y. but for now we need to know where everything goes before we start solving.

Best ResponseYou've already chosen the best response.0Oh then I'm not sure what would x sub 1 and y sub 1 equal to

Best ResponseYou've already chosen the best response.1Your ordered pair is (4,2) and we know that the ordered pair follows (x,y) so you're literally just taking the y and x value and plugging them in for your y1 and x1 values. or in other words y sub 1 and x sub 1.

Best ResponseYou've already chosen the best response.0Then what would we substitute in for the x and y values in the equation?

Best ResponseYou've already chosen the best response.0I thought you said we substitute those numbers in for x sub 1 and y sub 1

Best ResponseYou've already chosen the best response.1y  (y sub one) = m(x  *x sub one*) Look at the PSF equation again.

Best ResponseYou've already chosen the best response.0Ok so I'm substituting the coordinates and this is what I understand:\[2(2)=m(44)\]

Best ResponseYou've already chosen the best response.1No you only do it for y1 and x1, you don't substitute it in for ALL the variables.

Best ResponseYou've already chosen the best response.1Its going to look like y  2 = m(x  4) Now we have to substitute in the slope which is the value for m.

Best ResponseYou've already chosen the best response.1What does it tell you that the slope(m) is?

Best ResponseYou've already chosen the best response.0So how do I solve for both x and y?

Teddyiswatshecallsme

Best ResponseYou've already chosen the best response.1Exactly so what would our equation look like now?

anonymous

Best ResponseYou've already chosen the best response.0It would look like y  2 = 0(x  4)

Best ResponseYou've already chosen the best response.1Yes I am! Sorry.

Teddyiswatshecallsme

Best ResponseYou've already chosen the best response.1Yes it would look like that you are correct! Now do you know about the distributive property of multiplication?

Best ResponseYou've already chosen the best response.1he distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

Best ResponseYou've already chosen the best response.0So how would you use that when applying to the formula?

Teddyiswatshecallsme

Best ResponseYou've already chosen the best response.1SO basically you're going to DISTRIBUTE the 0 to the x and to the 4 and it becomes x because you're just distributing nothing

Best ResponseYou've already chosen the best response.0Oh like that! Sorry! It's harder to understand some of the terms.

Teddyiswatshecallsme

Best ResponseYou've already chosen the best response.1Yeah its a bit confusing sometimes so it because y  2 = x  4

anonymous

Best ResponseYou've already chosen the best response.0Wouldn't the 4 become a 0 when you are distributing?

Teddyiswatshecallsme

Best ResponseYou've already chosen the best response.1Now we need to do some order of operations to get that 2 over to the right side of the equation.

Best ResponseYou've already chosen the best response.1Well no. Because its like if i was giving out nothing. If i give you nothing and you have 4 dollars to begin with how many dollars are you left with?

anonymous

Best ResponseYou've already chosen the best response.0Still 4 dollars. But I thought anything multiplied with 0 will become 0.

anonymous

Best ResponseYou've already chosen the best response.0Aren't you multiplying in this case?

Teddyiswatshecallsme

Best ResponseYou've already chosen the best response.1Hmmm. Hold on. I need to do a bit of research. cx

Best ResponseYou've already chosen the best response.1Do you have multiple choice options?

Teddyiswatshecallsme

Best ResponseYou've already chosen the best response.1I believe you are correct. So that would end up being, y  2 = x So what do you need to do next?

anonymous

Best ResponseYou've already chosen the best response.0No I don't unfortunately. :/

anonymous

Best ResponseYou've already chosen the best response.0Put the 2 on the other side of the equal sign

anonymous

Best ResponseYou've already chosen the best response.0So the answer would be y = x + 2.

Teddyiswatshecallsme

Best ResponseYou've already chosen the best response.1You are correct!
