\[\text{ slope of line given two points}=m=\frac{\Delta y}{\Delta x}=\frac{y_1y_2}{x_1x_2}\] the points are \[(x_1,y_1) \text{ and } (x_2,y_2)\]

Hey slaaibak I understand pretty much what you said but for the first one I didn't get 1/3 I got 1/3? Following myininaya's rule m =\[\Delta y \div \Delta x\], the answer should be \[1\div3\] = 1/3?

Right so (2, 5) (1, 4) Between 2 and 1 there is 3 and between 5 and 4 there is 1. 1/3? What am I not seeing here??

If you look at the coordinates, while the x is increasing, the y decreases. the absolute value of the slope is 1/3, but because of the inverse relationship, it's a negative slope, since xdecreases and y decreases, therefore 1/3
