Answer:
-1.5, -1
Step-by-step explanation:
midpoint formula
(x1 + x2 / 2) , (y1 + y2/ 2)
-6 + 3 / 2 , -8 + 6 / 2
Answer/Step-by-step explanation:
Note:
<u>Graphing From An Equation: </u>
Equation are frequently written in slope-intercept form { y = mx+b}.
Which "m" represents the slope and "b" represents the y-intercept.
<u>Solutions and Equation:</u>
Solutions to linear equations contain any points located on the graphed line.
Ordered Pair = Solution to an equation if it's values are substituted in the equation which makes it true
Solve:
{x = 0 } 3(0) - 4y = 12
-4y = 12 (0, -3 )
-4y/-4 = 12/-4
y = -3
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
{y = 0} 3x-4(0) =12
3x = 12 (4,0)
3x/3 = 12/3
x = 4

Answer:
A
Step-by-step explanation:
under a reflection in the y- axis
a point (x, y ) → (- x, y ) , then
A (- 6, - 12 ) → B (6, - 12 )
Hey there! :D
The midpoint and the outside line are symmetrical to eachother, 2(BF)= AE
Two midpoint segments equals one AE segment.
So, use the representation above and plug in the numbers.
2(23)= 5x -4
56= 5x-4
Add 4 to both sides.
60=5x
Divide by the 5.
x=12
I hope this helps!
