which of the following could represent the side lengths of a triangle? check all that apply. A) 4ft, 7ft, 8ft B) 4in, 4in, 8in, C) 20m, 15m, 12m D) 13mm, 7mm, 9mm E) 6cm, 3cm, 8cm

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 answer is simply just 6n add the two together as they have an n

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
