Choose which property of equality is demonstrated moving from step a to step b. a. If b = 3, and m = 5, and y = mx + b then,

b. y = 5x + 3

What property is this??

anser is a

step-by-step explanation:

negitive slope

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

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

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
