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)

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
