1. find the coordinates of the midpoint between point a(18, -6) and the origin. 2. find the coordinates of the midpoint of jk if j (-9, 5) and k(21, -7). everyone!

The midpoint is given by finding the average x-value and the average y-value, thus the formula would be:

M = ( (x1 + x2)/2, (y1 + y2)/2 ), where (x1, y1) and (x2, y2) are two points on the graph

1. We have two points here, the origin - ie. (0, 0) - and A(18, -6). Thus, using the formula above for the midpoint we get:

M = ( (0 + 18)/2, (0 + (-6))/2 )

M = (18/2, -6/2)

M = (9, -3)

2. Using the same approach, we can find the midpoint for this question using the points J(-9, 5) and K(21, -7):

M = ( (-9 + 21)/2, (5 + (-7))/2 )

M = (12/2, -2/2)

M = (6, -1)

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

your answer is option c.
