Question

If (a, -2) lies on the graph of 3x-y=10then the value of a is

Answer 1

Answer:

X=a; Y=-2

3x-y=10

3(a)-(-2) =10

3a+2=10

3a=10-2

3a=8

a=8/3

Answer 2

Step-by-step explanation:

Hey mate,

Hope you understand

Given equation is 3x-y=10

And the line meets x-axis at a,

y-axis at -2

so,3x-y=10

3(a)-(-2)=10

3a+2=10

3a=10-2

3a=8

a=8/3
