This is because the line intersects the x-axis at the point (8,0)

Answer:

Step-by-step explanation:

$\frac{14}{7} =\frac{n}{21}$

Let us divide by 14 by 7 which is 2, so the equation is:

$2 = \frac{n}{21}$

Let us multiple 21 over the other side since 21 is in the denominator of the equation, so we get

$n = 21*2 = 42$

So the answer is 42.
