The three points are $\"\"$ .

\

To tell the three points lie on the same line, find the line equation by using two points and remaining point substitute in the line equation then the obtained statement is true.

\

Substitute the values of $\"\"$ in the slope formula $\"\"$ .

$\"\"$ . $\"\"$

\

To find the y - intercept, substitute the values of $\"\"$ in the slope - intercept from of equation $\"\"$ and solve for b.

\

The above statement is true. So three points $\"\"$ are lie on the same line. $\"\"$

\

Yes, the three points $\"\"$ are lie on the same line.
