Question

What? Slope of y=-13/pi

Answer 1

Since there is no x variable on the right hand side you are going to have a horizontal line at y = -13/pi

So what would you say the slope is here?

Answer 2

.........

Answer 3

oh......y intercept will always be -4.13 right?

Answer 4

Well at x = 1 it is y = -13/pi
at x = 2 it is y = -13/pi

If we use these two points (x, -13/pi) for (x1, y1)
and (x, -13/pi) for (x2, y2)

When we calculate slope: m = x2-x1/y2-y1 what do we get?
