The line equation in slope-intercept form is given by
where b is the y-intercept and m is the slope.
Then, we need to convert the given equation into the slope-intercept form. Then, by subtracting 10x to both sides, we have
and by dividing both sides by 2, we get
By comparing this result with the first equation, we can see that the slope is m= -5. So, the answer is: -5
