Answer 1

do u need answers or explanation

Answer 2

line which is parallel to y=-2x-7is in the form of
y= -2x +k

Answer 3

it passes through the point (3,1) so,substitute x=3 and y=1 in above equation to get k value

Answer 4

1=-2*3 +k
1=-6+k
1+6 =k
k=7
therefore ,required equation is y=-2x+7

Answer 5

2)W=6L+50

Answer 6

may i answer the third one?

Answer 7

why not sure

Answer 8

ArifL r u doing

Answer 9

wut?

Answer 10

answer to the third problem

Answer 11

it D

Answer 12

equation of the line passing through two points (x1,y1)=(2,9), (x2,y2) =(1,4) is
(y-y1)(x2-x1) =(y2-y1) (x-x1)

Answer 13

(y-9)(1-2) =(4-9)(x-2)
(y-9)(-1) =(-5)(x-2)

Answer 14

-y+9 = -5x+10
9-10 =-5x+y

Answer 15

-1= -5x+y
or
-5x+y =-1
i,e last one is the right option

Answer 16

is it clear

Answer 17

ty and so sorry i was not online ;-;
