Question

passing through (4,4) and parallel to the line whose equation is 2x+y-7=0 slope intercept form

Answer 1

parallel you should think same slope

Answer 2

You need to first find the slope of 2x+y-7=0

Answer 3

this will be the slope of the line you are trying to find.

Answer 4

You are also given a point on this other line that we want to find
that point being (4,4)

Answer 5

y-y1=m(x-x1)
so you have x1=4 and y1=4

Answer 6

so you only have to find the slope of that line i talked about and replace the m in our other equation

Answer 7

what happens to -7

Answer 8

put 2x+y-7=0 in y=mx+b form
this will give you information to obtain the slope of 2x+y-7=0

Answer 9

okay but what happens to the -7 or can please take me step by step please

Answer 10

2x+y-7=0

Answer 11

add 7 on both side and tell what u got ?

Answer 12

2x+y=7

Answer 13

gud

Answer 14

now subtract 2x from both side and tell me what u got ?

Answer 15

y=7-2x

Answer 16

very good

Answer 17

y=-2x+7

Answer 18

so here it is in standard form

Answer 19

in standard form coefficient of x = slope
so slope =??

Answer 20

2x

Answer 21

coefficeint of x =-2=slope

Answer 22

parallel line will have the same slope

Answer 23

y=-2x+c

Answer 24

now it is passing through (4,4)....so put x=4 and y=4 in above equation and tell methe value of c u got ?

Answer 25

y=2*(4)+4=12

Answer 26

loll.....y=4 and x=4 u have to put why u put c=4??

Answer 27

4=8+c

Answer 28

subtract 8 from both side

Answer 29

-4=c

Answer 30

wait equation was
y=-2x+c

Answer 31

4=-2*4+c
4=-8+c

Answer 32

add on each side

Answer 33

c=12

Answer 34

y=-2x+c
replace cby its value that will be your line

Answer 35

okay thanks but how did we get rid of the 7 in the equation?

Answer 36

you don't need the 7

Answer 37

okay

Answer 38

we know parallel lines have the same slope and different y-intercept

Answer 39

there is nothing we can do with the y-intercept from that equation to determine the y-intercept of the other equation

Answer 40

well except that we know they should be different

Answer 41

okay thanks for the help

Answer 42

y = -2x + 12 .
