anonymous · Answer

6x+5y=36
6x-5y=24 
i can't decide between them two ?
@nirmalnema

nirmalnema · Answer

mid points are..(1,6) and (7/2,3)
now by using two point formula you will get the equation of line
(y-y1)=m(x-x1)
m = (y2-y1)/(x2-x1)
= -6/5
(y-6)=-6/5(x-1)
5(y-6)=-6(x-1)
5y-30=-6x-6
6x+5y-36 is required equation

nirmalnema · Answer

sorry by mistake i deleted the previous solutions

anonymous · Answer

Which of the following when placed in standard position , lands in quadrant 4 ? 
, 256
-280
-5
135

anonymous · Answer

@nirmalnema do you know how to figure out that one ?

nirmalnema · Answer

in the 4 quadrant....
x is positive and y is negative
so what are these points of y axis or x axis..
can you plz give both the co ordinates together ..

anonymous · Answer

@nirmalnema they didn't give me both the coordinates together.

anonymous · Answer

@Akpellet_math do you know it ?

nirmalnema · Answer

so we cant say with any one co ordinate..
but still there are chances of -280 and -5 being in 4 quadrant

anonymous · Answer

yeahh ...the above efforts are correct ..:))

nirmalnema · Answer

it depends on there relative x co ordinates

anonymous · Answer

@nirmalnema  which one should I put ?

nirmalnema · Answer

sorry it cant be determined..without knowing x co ordinates..

anonymous · Answer

can you try to help me with one more before I just try to turn this test in ?

nirmalnema · Answer

yup sure... i will

anonymous · Answer

you will get the coordinates of X and Z as (1,6) and (3.5,3) respectively.
then you must apply the 2 point form of straight lines to get the equation ...$$\frac{ y-y1 }{ y1-y2 } =\frac{ x-x1 }{ x1-x2 }$$

anonymous · Answer

ABC has vertices A(0,0) B(3,3) C(6,0). Write the equation of the line containing the altitude AR in standard form .

anonymous · Answer

this is a different question  right .??  the previous answer is 4x+5y-34=0

anonymous · Answer

@Akpellet_math yes
