The following graph shows a proportional relationship.
What is the constant of proportionality between yyy and xxx in the graph?The following graph shows a proportional relationship.

2/3

Step-by-step explanation:

The constant of proportionality between y and x in this graph is 2.

Step-by-step explanation:

If the constant of proportionality of a proportional relationship is kkk, then:

y=kx

Let's pick a point on the graph to get the \blueD{x}and \maroonD{y}ystart color #ca337c, y, end color #ca337c-values. Then we can solve for

4=k*2

Let's divide both sides of the equation by 2 to solve for k

4\2=k*2/2

cross the both 2

Ant the answer is 2

The constant of proportionality between y and x in this graph is 2.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
