10x + 2y - 6 = 0
Multiply 5x + y - 3 = 0 by 2
2(5x + y - 3 = 0) = 10x + 2y - 6 = 0
Find the slope of the line passing throught the points (2, 2) and (4, 3).
The formula of a slope:

Substitute:

If the point (x, -1) lie on the same line, then the slope of line passing through the points (2, 2) and (x, -1) the same:
Substitute:

We have the equation:
<em>cross multiply</em>

<em>add 2 to both sides</em>

<h3>Answer: x = -4.</h3>
