Best ResponseYou've already chosen the best response.1can you identify the "slope" of the equation y=3/4x5?

Best ResponseYou've already chosen the best response.0@kaiters1010 what happens to the 5 :?

Best ResponseYou've already chosen the best response.1we are not changing the equation y=3/4x5, so nothing is gonna happen to 5. we are tying to find the equation of another line parallel to line y=3/4x5 so it will be in the form of y=3/4x+c and we need to find the 'c' we can use the information that 4,2 lies on the line y=3/4x+c so plug in x =4, y =2 in that 2 =3/4* 4 +c ! once you get the 'c' , you get the equation

Best ResponseYou've already chosen the best response.0and c is gotten like y=x+b correct?

Best ResponseYou've already chosen the best response.1you mean y = mx+b ? here m is the slope , b is the yintercept. we have slope = m= 3/4 here can you try to solve 2 =3/4* 4 +b to get the value of the yintercept 'b' ?

Best ResponseYou've already chosen the best response.1how did you get that?? 2 = (3/4)*4 + b 2 = 3 + b now add 3 on both sides :)

Best ResponseYou've already chosen the best response.0Oh which it would be 1 not negative

Best ResponseYou've already chosen the best response.1actually, lets do it step wise, 2 = 3 + b 2+3 = 3+3 +b 5 = 0 + b so b= 5 makes sense?

Best ResponseYou've already chosen the best response.0Yes It did in the beginning I mixed up on the negative positive bit.

Best ResponseYou've already chosen the best response.1so finally, we have the equation as y = 3/4 x + 5 :)

Best ResponseYou've already chosen the best response.1ahh, just read the question, we need the equation in "pointslope" form! which is \(y = y_1 = m (xx_1)\) and the point \(x_1, y_1 = 4,2 \) so the same equation would be \(y  2 = (3/4) (x 4)\)

Best ResponseYou've already chosen the best response.0So x1 nd y1 is the one i got from the one that is parallel ?

Best ResponseYou've already chosen the best response.1x1 and y1 are the coordinates that are given to you : (4,2)

Best ResponseYou've already chosen the best response.0then what about y and x I'm getting really confused :/

Best ResponseYou've already chosen the best response.0Would the solution be y−2=3/4(x−4)

Best ResponseYou've already chosen the best response.0I see and would that end of the question because it got very simple now

Best ResponseYou've already chosen the best response.1yep, thats all we had to do, find the slope, which was 3/4 and plug in the point! x1 = 4, y1 =2

anonymous

Best ResponseYou've already chosen the best response.0So basically the point slope form would be y2=3/4(x4

Best ResponseYou've already chosen the best response.0Ok I got 3 more questions I'll try to do myself if I have any questions would it be ok to tag you :?
