Answer: (-2,-4)
Step-by-step explanation:
To find the midpoint between two points we need to find the mean average between the x and the y .
Since we know the midpoint will have to represent the missing coordinates by the variables.
Solve for x to find the x coordinate by first multiplying both sides by -4.
-6 + x = -8 Add -6 to both sides
+6 +6
x = -2
The x coordinate of the B is -2 now we need to find the y coordinate.
Multiply both sides by 2
4 + y = 0 Subtract 4 from both sides
-4 -4
y = -4
The y coordinate is -4 so the coordinates will be (-2,-4)
Remember you can do anything to an eqautoin as long as you do oit to both sides
-5x=15
try to get 1x by itself
remember
(ax)/a=x when a=a
so
-5x=15
get x
divide both sides by -5
remember to flip sign
(-5x)/(-5)=15/(-5)
x=-3
answer is first one
x=-3
