Question

Find the slope of (0,1) and (2,7)

Answer 1

Slope= y2-y1
          x2-x1
So in this case 7-1=6
                       2-0=2
This makes the answer 3

Answer 2

Slope is $\frac { y_{2} - y_{1}}{ x_{2} - x_{1}}$

if we plug in your coordinates we get:
$\frac { y_{2} - y_{1}}{ x_{2} - x_{1}} \\ \frac {7-1}{2-0} \\ \frac {6}{2} \\ 3$

Therefore, the slope of (0,1) and (2,7) is 3.
