$$\text{Slope of a line passing through points } (x_1,y_1) \ and (x_2,y_2) \text{is given by}$$$$\large Slope= \frac{y_2-y_1}{x_2-x_1}$$

diyadiya · Answer

Now can you substitute the values and try it ?

anonymous · Answer

I'm really confused on this. /:

diyadiya · Answer

Its ok ,i can help you

diyadiya · Answer

line is passing through (6, 7) and (2, 9)

here x1=6   y1=7
        x2=2   y2=9
Now can you substitute it in the formula and find slope?

anonymous · Answer

So I think my answer would be C. -2.

diyadiya · Answer

how did you get that ? 
can you show me?

anonymous · Answer

I don't know how to solve this... so I'm just assuming so.

diyadiya · Answer

dont assume 
What's the formula for slope?

anonymous · Answer

y^2-y^1 over x^2-x^1

anonymous · Answer

$$y ^{2}-y ^{1} \over x ^{2}-x ^{1}$$

diyadiya · Answer

Its not squared ...

diyadiya · Answer

(6, 7)  is (x1,y1)
and 
(2, 9) is (x2,y2) 

Ok ?

anonymous · Answer

Oh oops! My bad!! Sorry about that.

diyadiya · Answer

Ok now what's x1 ,x2 ,y1 & y2 ?

anonymous · Answer

Idk
