We need to convert this equation to slope-intercept form first.
We can do that by solving for y.
x - 5y = 15
<em><u>Add 5y to both sides.</u></em>
x = 5y + 15
<em><u>Subtract 15 from both sides.</u></em>
x - 15 = 5y
<em><u>Divide both sides by 5.</u></em>
y = 1/5x - 3
We now know the slope is 1/5.
The slope of the line perpendicular to the line with a slope of 1/5 is -5.
The slope of a perpendicular line is the negative reciprocal of the original slope.
Using a graphing calculator, we know the y-intercept of the line that is perpendicular to the original line must have a y-intercept of -6 to run through the points (-2, 5).
The equation of the new line is y = -5x - 6.
1) 2x-1 or x=1/2
2) 5a-16 or a=16/5
Rate = 2 seats/11 minutes = 2/11 seats/min
Therefore the time required for s seats is

That is,
m = (11s)/2 min
When s = 16, obtain

When s = 19, obtain

Answers:

When s = 16, m = 88 min
When s = 19, m = 104.5 min
