Is the slope increasing or decreasing?

6. anonymous

decreasing

7. Jhannybean

alright, now you know the slope intercept form of a line is : $$y=mx+b$$ where $$b = \sf \text{y - intercept}$$

8. Jhannybean

and $$\sf \text{slope} = m = \dfrac{rise}{run}$$

9. Jhannybean

$m=\frac{y_2-y_1}{x_2-x_1}$ So if we were to use $$(x_1,y_1) \iff (9,0)$$ and $$(x_2,y_2) \iff (6,6)$$ could you find me the slope of the line?

10. hartnn

you mean (0,9) right?

11. Jhannybean

Ah yeah, typo. Sorry about that. $$(x_1,y_1) \iff (0,9)$$***
