Slope is the change in the y-value divided by the change in the x-value. So if we call slope the letter "m" then: \[m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\] So just pick one point as point 1 and the other as point 2 and then just subtract the y parts and the x parts and divide them!
well we know that to find out the slope of two form we use the \[y_{2} - y _{1} \div x _{2} - \]
\[x\]
The answer would be 3/11
