Question

1) To draw the graph of x-3y=1. Find y when x=7.​

Answer 1

Answer:

y=2

Step-by-step explanation:

x-3y = 1

7 - 3y = 1

7 - 1 = 3y

6 =3y

y = 2

Answer 2

The value of y is 2 when x=7.

Explanation:

To draw the graph of a line by using its equation $ax+by=c$, we randomly assign value for any one of the variable (x and y) , and find the value of other variable on it.

Similarly , to draw the graph of $x-3y=1$ , we can assign different values for x and check the value of y on it.

When x =7 , then put value of x in the given equation , we get

$7-3y=1$

$\Rightarrow\ 3y=7-1\\\\\Rightarrow\ 3y=6\\\\\Rightarrow\ y=2$

Hence, the value of y is 2 when x=7.
