Answer:

25%

Step-by-step explanation:

From the boxplot Given, an earning of $25 or less is represented on the boxplot as the lower quartile of the distribution which is the point at the start of the box. The lower quartile value is the percentage value up to 25% that is the first 25% of the distribution.

Hence, the percentage required = 25%

X + 2y = 6
2y = -x + 6
y = -1/2 x + 3 so slope = -1/2

parallel lines has same slope = -1/2
perpendicular lines slope is opposite and reciprocal so slope = 2
if slope not equal either -1/2 or 2 then neither.

y = -1/2 x - 5 ....m= - 1/2.... parallel

-2x + y = -4
y = 2x - 4...m = 2 ....perpendicular

-x + 2y = 2
2y = x + 2
y = 1/2 x + 1 ...m = 1/2 ...neither

x + 2y = -2
2y = -x - 2
y = -1/2 x - 1 ...m = -1/2 .....parallel

hope it helps
