Answer:

Step-by-step explanation:
Hi there!
We are given the line segment, with the end points AB
The coordinates of A are (-5, -4), and the coordinates of B are (-3, 3).
We want to find the midpoint of the line segment AB
The midpoint formula is given as
, where
and
are coordinates
We have two coordinates, which is what we need, but let's label their values to avoid any confusion:

Now substitute those values into the formula:


Now simplify the numerator and denominator

Simplify again:
The midpoint is (-4,
)
Hope this helps!
Answer:
x = 9
Step-by-step explanation:
38 = 6x - 16
Situate the x to one side -6x = -16-38
-6x = -54
-x = -9
x = 9
Answer:
if x=2, y= 1
if x=5, y=-5
Step-by-step explanation:
6x+3y=15
3y=-6x+15
y=-2x+5
y=-2(2)+5
y=-4+5
y=1
y=-2(5)+5
y=-10+5
y=-5
