Question

Does the point (2,-1) lie on the line y=3-2x?

Answer 1

Answer:

yes

Step-by-step explanation:

the line passes through that point.

Answer 2

Answer:

yes

Step-by-step explanation:

Here, x=2 and y=-1

If these points lie on the line y= 3-2x,then they must satisfy the equation of the line (also mean they must be equal)

So on solving the equations putting the value of x and y, we get

y=3-2x

or,-1=3-2*2

or,-1=3-4

Therefore, -1=-1
