Best ResponseYou've already chosen the best response.0Attempt to solve for x! (4,y) and (7,6); slope:4

Best ResponseYou've already chosen the best response.1\[\frac{ 6y }{ 74 }=4\] \[\frac{ 6y }{ 3 }=4 \] I just set it up like the normal slope equation, (y2y1)/(x2x1). Now just see if you can solve for y.

Best ResponseYou've already chosen the best response.0Olay, let me try it out for myself to see if I understand it

Best ResponseYou've already chosen the best response.0Wait, I get 6 / 3 how did you get 4?

Best ResponseYou've already chosen the best response.1You said the slope = 4, right? Well, the result of (y2y1)/(x2x1) is slope. But we already have the slope, so I just set the equation equal to 4.

Best ResponseYou've already chosen the best response.0Ahhhhhh okay I see how you set it up!

Best ResponseYou've already chosen the best response.0And then you subtract the bottom, correct?

Psymon

Best ResponseYou've already chosen the best response.1Yeah, which left me with \[\frac{ 6y }{ 3 }=4 \]Would you know how to use that to solve for y?

Best ResponseYou've already chosen the best response.0My guess is that I multiply 6 and 3

Psymon

Best ResponseYou've already chosen the best response.1Just multiply both sides by 3 to start.

Psymon

Best ResponseYou've already chosen the best response.1That will cancel the 3 out of the denominator of the fraction.

Best ResponseYou've already chosen the best response.0So would it be 18+3y=4

Psymon

Best ResponseYou've already chosen the best response.1Nah. Okay, so we multiply both sides by 3 and it looks liek this: \[\frac{ 3(6y) }{ 3 }=4(3)\]From here, the 3's on the left cancel out and 4 and 3 multiplies to get: \[6y = 12 \] Kinda see why?

Best ResponseYou've already chosen the best response.0Yea aha I sorta do, it's because I got 183y=12 when I multiplied it by 3

Best ResponseYou've already chosen the best response.1Yeah, but you dont multiply the 6 and the y by 3. Because you have a 3 on top and bottom, they cancel out and become 1. That is the whole purpose of multiply by 3 is because itll get rid of the denominator. It's just like if we had: \[\frac{ x }{ 3 }=3 \]Because x is divided by 3, to get it by itself we do the opposite operation and multiply by 3. dw:1378605836732:dw Same thing with our problem: dw:1378605874087:dw

Best ResponseYou've already chosen the best response.0Ahhhhhh okay I see now! And then after I get 6y=12 I add 6 to both sides

Best ResponseYou've already chosen the best response.0When I divide y to both sides, would I be dividing y or just y?

Psymon

Best ResponseYou've already chosen the best response.1Well if you have y = 6, it does no good to divide by y or y. If you divided by y you get: \[1=\frac{ 6 }{ y } \] You just want to divide by 1 is all to get y by itself.

Best ResponseYou've already chosen the best response.0And the final answer will be y=6

Best ResponseYou've already chosen the best response.1Bingo. Can even test it :3 \[\frac{ 66 }{ 74 }=\frac{ 12 }{ 3 }=4 \] So yep, works :3
