Determine which of the lines, if any, are parallel or perpendicular. Explain. 9. The lines pass through the following points:
Line a: (1, 5) and (-2, -4)
Line b: (3, 2) and (1, -4)
Line c: (6, 1) and (-4, 2)

10.
Line a: 4y - 12x = 20
Line b: 3y = -x + 2
Line c: y = 3x - 1

step-by-step explanation:

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
