A. Yes, because all of the pairs represent the same ratio.
O B. No, because only one of the pairs is a simplified ratio.
O C. No, because the y-values are not increasing at a constant rate.
O D. Yes, because as x increases, y increases.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.

are ya tryin to ask something or is this a statement
