Answer:
y=4x and x+4y=12 are perpendicular because they have opposite reciprocal slopes
Step-by-step explanation:
y=4x slope is 4
x+4y=12 slope is -1/4
If you plug in the # the only one that is correct is y-8=-0.2(x+10)
6(n+8)=2
6n + 48 = 2
6n + 48 - 48 = 2 - 48
6n = -46
N = -46/6
N = -7 2/3
The mistake Shawna made was in her answer the 54 repeats so the bar should be over the .54 not the .545
