One point of the line is given to be (5, -1) and second point is the y-intercept of the line x - 3y = 6

We can write this equation as:

$x-6=3y \\ \\ 
y= \frac{1}{3}x-2$

So, the y-intercept of the line is -2.

Now we have two points for the new line (5, -1) and (0, -2). Using these we can find the slope

$Slope=m= \frac{-2+1}{0-5}= \frac{1}{5}$

Using the slope and the point (0, -2) we can write the equation in slope intercept form as:

$y= \frac{1}{5}x-2$

Thus the answer to this question is option C. Slope for the new line is 1/5 and the y-intercept is -2

A flea is sitting on the very tip of the minute hand on a grandfather clock. The minute hand measures 6 inches long. How far doe

12345 [234]

In one day there are 24 hours, and each hour there are 60 minutes, so the minute hand makes 24*60=1440 full circles in one day. For each circle, the tip of the minute hand travels the entire circumference, which is 2*pi*r = 2*pi*(6 inches) = 12*pi inches. Multiplying by 1440 circles per day gives a distance of:
17280*pi inches, or 54,287 inches.
