What is the midpoint of the line segment -1, 2 and 9, 5

So if I did my math right it should be (4,3.5)

Step-by-step explanation:

The formula for finding a midpoint of a segment is (x1+x2/2 , y1+y2/2)

So first you grab both x's out of (-1,2) and (9,5).

So -1 and 9.

Then you add them and divide them by 2 to get 4

Then you grab the y's out of (-1,2) and (9,5)

So 2 and 5.

Add 2 and 5 together and divide them by 2.

That's when you should get 3.5

So the midpoint should be (4,3.5)

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

what is the model?
