Answer:
x=1
y=-4
Step-by-step explanation:
4x+y=0 -> y= -4x
2(-4x)+x=-7
-8x+ x=-7
-7x=-7
x=-7/-7=1
y=-4 . 1 = -4
For the midpoint, you find the differences in x values and y values then divide them by 2. Like so:
Let's do x first:
(-16-0)/2 = (-16)/2 = -8
So our x coordinate is -8.
Now Y:
(-16)/2 = -8
So our Y coordinate is -8 as well.
So your answer is:
(-8,-8)
