Are two lines parallel, perpendicular or neither 3x+7y=15 and 7x-3y=6

The lines are perpendicular

Step-by-step explanation:

we know that

If two lines are parallel, then their slopes are equal

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

we have

----> equation A

isolate the variable y

Divide by 7 both sides

The slope of the line A is

----> equation B

isolate the variable y

Divide by 3 both sides

The slope of the line B is

Compare the slope of both lines

so

----> the lines are not parallel

Find the product of the slopes

----> the lines are perpendicular

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
