Question 1120390
delta x means change in the value of x.
delta y means change in the value of y.


you have 2 points.
they are (5,2) and (7,-11)


slope is equal to (y2-y1) / (x2-x1)


let the point (5,2) be equal to (x1,y1)
let the point (7,-11) be equal to (x2,y2)


slope is equal to (y2-y1) / (x2-x1) = (-11 - 2) / (7 - 5) = -13/2.


-13/2 is equivalent to -6.5 in decimal form.


change in the value of x is equal to (x2 - x1) = (7 - 5) = 2


change in the value of y is equal to (y2 - y1) = (-11 - 2) = -13.


your solutions are:


change in the value of x is equal to 2
change in the value of y is equal to -13
slope is equal to -6.5
