Question

graphically Daya pair of linear equation 7 x minus Y is equal to 5,21 x minus 3 Y is equal to 10 represent two lines which are​

Answer 1

Step-by-step explanation:

GIVEN :

The pair of equations are 7x-y=5 and 21x-3y=10

TO FIND :

Graphically, the pair of equations 7x-y=5 and 21x-3y=10 represents which two lines.

SOLUTION :

Given pair of equations are 7x-y=5 and 21x-3y=10

From the given pair of equations are 7x-y=5 and 21x-3y=10 we get that

the 2nd equation 21x-3y=10 can be written as below

3(7x-y)=10

7x-y=\frac{10}{3}7x−y=

3

10

Comparing the equations we get that their slopes are equal and never intersect.
