Two points A (-2, 9) and B (4, 8) lie on a line l. Find the slope of the line l.

the slope is -1/6

Step-by-step explanation:

you subtract the y values and the x values.

9-8=1

-2-4=-6

-1/6 or 1/-6 (either way the fraction is negative, but the first way is the way that I would show it)

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
