The equations of three lines are given below. Line 1: 6x-4y=6 Line 2: -2y=3x+5 Line 3: y=-2/3x+7 For each pair of lines, determine whether they are parallel, perpendicular, or neither.

Line 1 and Line 2: Neither -- slopes are not same (one is negative one is positive)

Line 1 and Line 3: Perpendicular -- Line 3's slope is the negative reciprocal of Line 1's

Line 2 and Line 3: Neither -- different slopes

Step-by-step explanation:

Lines are parallel if they have the same slope but different y-intercept.

Lines are perpendicular if the slopes are negative reciprocals.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
