The constant of proportionality that lies in all of the pairs of values that we have here is given as 17.5
What is the constant of proportionality?This is the term that is used to refer to the ratio that is known for the fact that it helps to relate two values that are given in a proportional way.
For instance we are to find the constant proportionality of (9, 148.50)
This is given as 9 + 148.5 / 9
= 157.5 / 9
= 17.5
Then the second pair is (15 ,247.50)
In the same way 15 + 247.50 / 15 = 17.5
Hence we can see that the constant of proportionality in all of the pairs is 17.5

write an equation of the line in the point- slope form that passes through the given points in the table. Then write the equation in slope-intercept form. (10,80) (5,65)
To write the equation of the line that passes through (10,80) (5,65)
we will use the formula;
[tex]y-y_1\text{ =}\frac{y_{2-}y_1}{x_2-x_1}(x-x_1)[/tex]x₁ = 10 y₁ = 80 x₂ = 5 y₂ = 65
substituting the above into the formula;
[tex]y\text{ - 80 = }\frac{65\text{ - 80}}{5\text{ - 10}}(\text{ x - 10)}[/tex]we will go ahead and simplify
[tex]y\text{ - 80 = }\frac{-15}{-5}(x-10)[/tex]y- 80 = 3(x - 10)
y- 80 = 3x - 30
y -3x -80 + 30 = 0
y - 3x - 50 = 0
The above is the equation of the line.
To write in a slope-intercept form simply means to write it in the form;
y = mx + b
where m is the slope and b is the intercept
Hence;
y = 3x + 50
The above is the equation of the line in a slope-intercept form

The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠K is 168° so option (A) is correct.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 sides and three angles in every triangle, some of which may be the same.
It is known that the sum of all three angles inside a triangle will be 180°.
So, m∠J + m∠L + m∠K = 180°
m∠K = 180° - 78° - 90°
m∠K = 12°.

x = 36° (option C)
Explanation:The adjacent angles in a parallelogram are supplementary. This means the sum of the angles is equal to 180 degrees
The adjacent angles in this paralllelogram are (4x + 2)° and 34°
(4x + 2)° + 34° = 180°
4x + 2 + 34 = 180
4x + 36 = 180
4x = 180 - 36
4x = 144
Divide both sides by 4:
4x/4 = 144/4

(0, 1) and (2, 2)
The equation of the line passing through points (0,1) and (2,2) will be y = ( 1 / 2) x + 1
What is an equation of the line?
An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope= 2-1 / 2-0 = 1 /2
Now pick one of the points and put in for y and x use (2,2).
2= 1/2(2) +b
2=1 + b
2-1 =1-1 +b subtract 1 from each side
1 = b This is your y-intercept
The equation will be written as:-
y = ( 1 / 2) x + 1

The dimensions of the cylinders are given inunits.Cylinder 1Cylinder 238What is the volume of cylinder 2?
Since the two cylinders are congruent, it means that their dimensions are exactly the same thing.
In other words, the radius of cylinder 1 is the same as that of cylinder 2, and the height of cylinder 2 is the same as that of cylinder 1. This is what it means for two solid shapes to be congruent.
Now, to find the volume of cylinder 2, we apply the frmula for the volume of a tyical cylnder:
[tex]\text{Volume}=\pi\times r^2\times h[/tex]Now,
radius of cylinder 2 = radius of cylinder 1 = 3
height of cylinder 2 = 8
Thus: r = 3, h= 8
Therefore:
[tex]\begin{gathered} \text{Volume}=\pi\times r^2\times h \\ \text{Volume}=\pi\times3^2\times8 \\ \text{Volume}=\pi\times9^{}\times8 \\ \text{Volume}=\pi\times72 \\ \text{Volume}=72\pi\text{ cubic units} \end{gathered}[/tex]Therefore the volume of cylinder 2 is 72pi cubic units (Option D)
