Question 726663
Two generic points that define a straight line are (x1, y1) and (x2, y2)


In this case, (x1, y1) = (6,  7), which means x1=6 and y1= 7


and (x2, y2) = (9,  2), which means x2=9 and y2= 2


So x1=6, y1= 7, x2=9, and y2= 2.


----------------------------------------------------------------



Now use the slope formula



m = (y2-y1)/(x2-x1)



m = ( 2- 7)/(9-6)



m = -5/3



So the slope of the line that passes through the two points is  -5/3
