Answer:
(1, 3)
Step-by-step explanation:
Given coordinates of 2 endpoints, G(-2, 5) and H(4, 1), midpoint of AB is calculated as shown below:
Midpoint (M) of GH, for G(-2, 5) and H(4, 1) is given as:
Let
Thus:
Coordinates of the midpoint of GH = (1, 3).
Answer:
(-7,2)
Step-by-step explanation:
3x+8y=-5
-2x+2y=18
so first of all, you want either x or y to be the same for both equations <em>(it can be negative or positive but has to be the same number)</em>
to do that, we'll multiply them:
I'll do y because it is easier
(-2x+2y=18) 4
<u>-8x+8y=72</u>
<u>3x+8y=-5
</u>
the y's now match
let's subtract them because they're both positive
-8x - 3x = -11x
8y - 8y = 0
72 - (-5) = 77
so -11x = 77
which results to x = -7
now we need the y.
to do that, we simply plug in the x in any of the equations:
-2x+2y=18
-2 (-7) + 2y = 18
14 + 2y = 18
2y = 4
y = 2
so the answer is (-7,2) if you're looking for a point
