Question

Given the equations of lines as

Line L1: y = px - 4
Line L2: y = 4x - 1
Line L3: y = sx - 9
Line L4: y = -3x - 10
Line L5: y = dx - 10

Find p, s, and d such that L1 and L2 are parallel, L3 and L4 are perpendicular, and L1 and L5 are parallel.

what do i do?

Answer 1

p = 4

Answer 2

s = 1/3

Answer 3

d = 4

Answer 4

how'd you get that?

Answer 5

simple.

Answer 6

parellel lines hav same slope.

Answer 7

perp lines hav slope, formule:

m1 x m2 = -1

Answer 8

thanks you(:
