Answer
		
three fourths
		
-negative three fourths
		
four thirds
		
-negative four thirds

lalaly · Answer

$$\underline{slope}=\frac{y_2-y_1}{x_2-x_1}$$

DD: I have no idea what that means.

Wouldn't that end up being?

x/y?

lalaly · Answer

the points you have are $$(x_1,y_1) -> (1,5) $$$$(x_2,y_2)-> (5,2)$$

anonymous · Answer

Yes but now what?

lalaly · Answer

substitute those points in the slope formula

Wait, what?
