Question

Is (2,7) a point on the line y=4x-3?

Answer 1

Given that the equation of the line is $y=4x-3$

We need to determine the point (2,7) lies on the line.

For a point to lie on the line, substituting the point in the equation of the line makes it valid.

Thus, substituting the point (2,7) in the equation of the line $y=4x-3$, we get;

$7=4(2)-3$

$7=8-3$

$7\neq 5$

Thus, the both sides of the equation are not equal.

Substituting the point (2,7) in the equation makes the equation invalid.

Thus, the point (2,7) does not lie on the line  $y=4x-3$
