Answer:
-4y=11x-33
Step-by-step explanation:
3x-2y-16=-17+14x+2y
-2y-2y=14x-3x-17+16
-4y=11x-33
The first one is correct!

Step-by-step explanation:
You can tell from the direction of the arrows. They represent parallel.
Answer:
a) (-1,4.5)
b)10.63 units
c)7/8
Step-by-step explanation:
a) To find this, we use the midpoint formula
(x,y) = (x1 + x2)/2 , (y1 + y2)/2
(x1,y1) = (3,8)
(x2,y2) = (-5,1)
(x,y) = (3 -5)/2 , (8 + 1)/2 = (-1, 4.5)
b) To calculate the distance D between two points, we use the formula;
D = √(x2-x1)^2 + (y2-y1)^2
D = √(-5-3)^2 + (1-8)^2
D = √(-8)^2 + (-7)^2
D = √64 + 49
D = √113
D = 10.63 units
C) We use the slope formula here
m = (y2-y1)/(x2-x1)
m = (1-8)/(-5-3) = -7/-8 = 7/8
Answer:
Step-by-step explanation:
(x - 3)/2 = -1
x - 3 = -2
x = 1
(y + 7)/2 = -1
y + 7 = -2
y = -9
(1, -9) the other endpoint
