Answer:
The correct option to tell whether a relationship is proportional or not is;
Step-by-step explanation:
A proportional relationship is a relationship between two variables, 'x', and 'y' such that they have equivalent ratio, such that all values of variable 'y' are given by the product of the values of the variable 'x' and a constant, 'k'
Therefore, y = k · x, from which we have;
Therefore we can use to tell whether a relationship is proportional or not proportional.
Answer:
(9, 5
) or (9 1/2, 5 1/2) (same things, just typed two different ways)
Step-by-step explanation
I can't remember the midpoint formula so I'll use a different method to get the midpoint.
since the ratio of a midpoint is 1:1 and that as a fraction is 1/2, we can take these coordinates and designate which one is first and which one is second (12, 2) will be my second and (7,9) will be my first. The formula I will use will be , so 1/2( 12 - 7) +7. now distribute the 1/2 to both the numbers
or
. The same works with the Y values, which would equal up to 5.5 or 5
