Question

Write the standard form of the equation of the line that passes through the point(4,1)
and is parallel to the line 3x+3y=5

Answer 1

3(x+y)=5
x+y=5/3
y=-x+5/3
so slope is -1.coefficient of x is alwas the slope
now requird equn will be...(y-y1)=m(x-x1)
where(x1,y1) is the given point and m is the slope

Answer 2

maam/sir.. i guess i already got the answer

Answer 3

can i ask one more?

Answer 4

sure

Answer 5

Solve the given linear system
2x-y-z=5
x+y+z=7
3x-2y-3z=1

Answer 6

u need it by which method?

Answer 7

uhm.. substitution..?

Answer 8

2x-5=y+z
now put the value of y+z in seocnd equation,
x+(2x-5)=7

Answer 9

can u solve dis one and find the value of x?

Answer 10

i already found the value of x

Answer 11

x=4

Answer 12

but the thing is i dont know what to do next..

Answer 13

see,now put the value of x in any two equations and solve for y and z.first substitute in any 2 eqns

Answer 14

uhmm can you do it for me and explain how?

Answer 15

i m tconsidering these 2 equations,
x+y+z=7
first we put value of x in dis eqn,
4+y+z=7
y+z=7-3
y+z=4.........(1)
another eqn is,
3x-2y-3z=1
now putting the value of x in dis eqn,we get
3*4-2y-3z=1
12-1=2y+3z
11=2y+3z.........(2)

Answer 16

now u jst need to solve these 2 eqns and get the value of y and z

Answer 17

how did the 4 became 3 in eq. 1?

Answer 18

i still can't get it :/

Answer 19

can you solve it?

Answer 20

for me? so i can answer some of the items for tomorrows long quiz? :/

Answer 21

multiply eqn 1 by 2,we get
2y+2z=8
now subtracting dis eqn frm 2nd eqn,
