Answer 2

Step-by-step explanation:

Solutions:-

A)

y=x is the equation which passes through the origin.

B)

i)Equation of y -axis is x = 0

ii)Given equation is x+ky = 3

If x = -1 and y = 2 then

=> -1+k(2) = 3

=> -1+2k = 3

=> 2k = 3+1

=>2k = 4

=> k = 4/2

=> k = 2

The value of k = 2

iii)Given equation is x+2y = 7

It is a linear equation in two variables

So it has infinitely number of many solutions.

iv)Equation of x-axis y=0

C)

Given equation is 6x+5y = -1

=> 6x+5y+1 = 0

It is in the form of ax+by+c = 0

a = 6

b = 5

c = 1

D)

Given equation is x+y = 4

Put x = 0 then

=> 0+y = 4

=> y = 4

Solution (0,4)

Put y = 0 then

=> x+0 = 4

=> x = 4

Solution = (4,0)

Put x = 1 then

=> 1+y = 4

=> y = 4-1

=> y = 3

Solution = (1,3)

Put y = 1 then

=> x+1 = 4

=> x = 4-1

=> x = 3

Solution = (3,1)

Scale :- On X-axis 1 cm = 1 unit

On Y-axis 1 cm = 1 units
