A proportional relationship is used to illustrate linear equations.
The constant of proportionality is 3
From the table, we have the following points:
(x,y) = (2,6) (3,9)
The constant of proportionality is calculated using:
So, we have:
Subtract
Divide
Hence, the constant of proportionality is 3

Answer:
280 plants
Step-by-step explanation:
For 2 boxes it would be 70 plants so if you divide 70 by 2 that would equal 35, and you trying to figure out how much plants are in 8 boxes so you multiply 35x8.
35x8=280
Answer:
First, we need to determine the slope of the line going through the two points. The slope can be found by using the formula:
m
=
y
2
−
y
1
x

−
x
1
Where
m
is the slope and (
x
1
,
y

) and (
x
2
,
y
2
) are the two points on the line.
Substituting the values from the points in the problem gives:
m
=

Now, we can use the point-slope formula to find an equation going through the two points. The point-slope formula states:
(
y
−
y

)
=
m
(
x
−
x

)
Where
m
is the slope and
(
x

y

)
is a point the line passes through.
Substituting the slope we calculated and the values from the first point gives:
(
y

)
=

(

)
We can also substitute the slope we calculated and the values from the second point giving:
(
y

)
=

(

)
We can also solve the first equation for
y
to transform the equation to slope-intercept form. The slope-intercept form of a linear equation is:
y
=
m
x
+
b
Where
m
is the slope and
b
is the y-intercept value.

2,1 i got you all i want in return is a Brainlyist
first you have to see what you need to multiply it by so you divide 24 by 8 which gets you 3. then you divide 45 by 3 and that gets you 15 so she has to rake the yard 15 times.
