Answer:
Step-by-step explanation:
With any two points, you can find the line between them with:
#1:
(-1, 1) -> (1, 3)
(3, 4) -> (0, 2)
(0, 1) -> (3, 3)
Lines b and c are parallel because they have the same slopes
#2 is a bit easier
a: 2y = x + 12,
b:2y - x = 5,
c: 2y + x = 4,
Since lines a and b have the same slope, they are parallel
#3:
(1, 3), y = 2x - 5
We have to find a line with a slope of 2 that passes through the two points
#4:
(-2, 1) , y = -4x + 3
We have to find a line with a slope of-4 that passes through the line
#5:
(-2, 3) (1, -1),
(-3, 1) (1, 4),
(0, 2) (3, -2)
Since lines c and b have negative reciprocal slopes, they are perpendicular
#6:
a: y = -4x + 7
b: x = 4y + 2,
c: -4y + x = 3,
since lines a and c have negative reciprocal slopes, they are perpendicular
