Hey there :)
To find the slope with <em>two points</em> we will need to use the equation
( 3 , -20 ) ( 5 , 8 )
Here is what the equation should look like when replaced with the numbers (<em>it will be a fraction</em>) :
We know that <em>two negatives</em> cancel out and make a positive, so the numerator would actually be 8 + 20.
Solve the fraction and we get
28 <em>divided</em> by 2 is 14. The slope is 14.
