Question

tutorials on line ..all invited

Answer 1

first of all the general equation of line

Answer 2

ax+by=c

Answer 3

:/

Answer 4

where a,b,c are constant

Answer 5

im confused

Answer 6

what is everybody doing here?

Answer 7

haha

Answer 8

standard equation of line

Answer 9

y=mx+c

Answer 10

here
m= slope of line

Answer 11

c= y intercept

Answer 12

now first thing how to calculate slope of line

Answer 13

we are given two point here

Answer 14

how to find slope thn ???

Answer 15

\[m=\frac{ y2-y1 }{ x2-x1}\]

Answer 16

here we take y coordinate in numerator

Answer 17

we took y2 first and subtracted y1 from it

Answer 18

we will do similar in denominator
we will take x2 and will subtract x1

Answer 19

how to form equation of line from these 2 given point

Answer 20

pick any one point ..hmmmm...lets pick (x1,y1)

Answer 21

equation of line will be
y-y1=slope*(x-x1)

Answer 22

u can also pick (x2,y2) instead of (x1,y1)

Answer 23

slope we calculated above

Answer 24

\[y-y1=\frac{ y2-y1 }{ x2-x1 }(x-x1)\]

Answer 25

this is called POINT SLOPE FORM

Answer 26

now the standard form of equation
y=mx+c

Answer 27

lets consider a equation
y=2x-4

Answer 28

on compairing with y=mx+c
we can see m=2

Answer 29

so slope=2

Answer 30

now how to find y intercept and x intercept of line

Answer 31

to calculate y intercept
put x=0 in line equation

Answer 32

y=2*0-4
y=0-4

Answer 33

y=-4

Answer 34

so our y intercept =-4

Answer 35

now x intercept

Answer 36

to find x intercept put y=0
0=2x-4

Answer 37

add 4 on both side
4=2x and now divide by 2 on both side

Answer 38

2=x it is our x intercept

Answer 39

now remember few things

Answer 40

x=2

Answer 41

1. parallel line have same slope

Answer 42

y=2x-4
line parallel to this will have same slope

Answer 43

that is slope =2

Answer 44

2.product of slope of perpendicular line =-1
m1*m2=-1

Answer 45

m1=slope of first line
m2=slope of 2nd line or perpendicular line

Answer 46

thatzz it guyss
thankuu

Answer 47

any doubt regarding this??

Answer 48

nope not me

Answer 49

gorv btw how do u get human cac?

Answer 50

okk buddy:)

Answer 51
