im kinda understanding but not fully

welshfella · Answer

do you get  the first one?

welshfella · Answer

item 1?

anonymous · Answer

yes

welshfella · Answer

basically for item 2 you are seeing how changes in value of y relate to corresponding changes in value of x

rate of change =    y2 - y1
                             ------
                               x2 - x1

where x1 and y1   and x2 and y2 are corresponding values

welshfella · Answer

referring to the table:-

x1 = 0 , y1 = 1

x2 = 2, y2 = 1.4
