9 boys spent between 0.5 hour and 0.75 hour on the site
To tell whether the <span>the sequence is arithmetic, we try to see if there is a common difference between the terms in the sequence. We do as follows:
1 1/2 - 1 1/3 = 1/6
1 1/3 - 1 1/6 = 1/6
Therefore, the sequence is arithmetic and the common difference is 1/6. Hope this answers the questions. Have a nice day.</span>

Slope of the line h is 2.
The equation for line h is y = 2x + 4.
Solution:
General equation of a line is y = mx + c,
where m is the slope of the line and c is the y-intercept.
In the given image, line g and line h are intersecting lines and perpendicular to each other.
Equation of line g is
.
Slope of the line g (
) = 
If two lines are perpendicular, then the product of the slopes is –1.
⇒
