Answer: 28x+42y=3
Step-by-step explanation:
Given: The point (x,y) is equidistant from the points .
By distance formula the distance between is
Similarly, the distance between is
Since,
Answer:
A
Step-by-step explanation:
slope of the given line: -a/b
-4/-2 = 2
realtionship between the slopes of two perpendicular lines:
m = -1/m
slope of the second line
-1/2
line
y-y1 = m(x-x1)
y - 6 = -1/2(x-4)
y = -1/2x + 2 + 6
y = -1/2x +8
