Idon't understand how to find slope, can someone me with the problems circled in blue? !
(show your work )

the equation to find any slope given two points is (y1-y2)/(x1-x2)

given this equation, the slope of problem 24 would be (6-3)/(-1-4) or (3-6)/(4+1) which is equal to -3/5,

depending on which point you call (x1,y1) and (x2,y2)

calling either of the points 1 or 2 will still result in the same slope

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
