Answer:
y=-1/2x+1
Step-by-step explanation:
2x+4y=16
4y=-2x+16
y=-1/2x+4
y=mx+b, m=-1/2, x=4, y=-1
-1=(-1/2)(4)+b
-1=-2+b
1=b
y=-1/2x+1
Answer:
point A coordinates are (-2,-6)
Step-by-step explanation:
Point A (-2,y)
point B (4,2)
x_1= -2, y_1= y_1 (unknown)
x_2= 4, y_2=2
distance=10
using the formula for distance between two points;
distance=
10=
10=
square both sides
