Answer:
subtract the 4 from one side
divide the -2 from the y and the-2x and 4
-y + 6 = x
subtract the 6 and add -6 after the x
6x - y - 3 = 0
add the y so it cancels out
y = 6x - 3
3y + 15x = -15
subtract the 15x
3y = -15x - 15
divide the 3
y = -5x -5
B
Step-by-step explanation:
perpendicular
Answer:a
the distance formula is d= (x2−x1)²+(y2−y1)²
so plug in d=(3+4)²+(-6-4)²
simplify d=(7)²+(-10)²
d=49+100
d=149
