PLEASE HELP ASAP I NEED THIS NOW Sara graphs a line passing through points that represent a proportional relationship. Which set of points could be on the line that Sara graphs?A). (2,4),(0,2),(3,9)
B). (6,8),(0,0),(18,24)
C). (3,6),(4,8),(9,4)
D). (1,1),(2,1),(3,3)

Answers

Answer: Option B.

Step-by-step explanation:

By definition, the graph of a proportional relationships is a straight line that passes through the origin (Remember the the origin is at $(0,0)$ ).

Then, the equation have the following form:

$y=kx$

Where "k" is the constant of proportionality (or its slope)

Then, since the Sara graphs a line that represent a proportional relationship, you can conclude that the line must pass through the point $(0,0)$ .

Then:

The set of points in Option A could not be on that line, because when $x=0,y=2$

The set of points $(6,8),(0,0),(18,24)$ (Given in Option B) could be on the line that Sara graphs, because it has the point $(0,0)$

For the set of points shown in Option C and Option D, you can check if the slope is constant:

$C)\ slope=(y)/(x)\n\na)\ slope=(6)/(3)=2\n\nb)\ slope=(8)/(4)=2\n\nc)\ slope=(4)/(9)$

Since the slope is not constant, this set of ponts could not be on the line.

$D)\ slope=(y)/(x)\n\na)\ slope=(1)/(1)=1\n\nb)\ slope=(1)/(2)$

Since the slope is not constant, this set of ponts could not be on the line.

Set of points that could be on the line that Sara graphs are:

Option B). (6,8) , (0,0) , (18,24)

Solving linear equation mean calculating the unknown variable from the equation.

Let the linear equation : y = mx + c

If we draw the above equation on Cartesian Coordinates , it will be a straight line with :

m → gradient of the line

( 0 , c ) → y - intercept

Gradient of the line could also be calculated from two arbitrary points on line ( x₁ , y₁ ) and ( x₂ , y₂ ) with the formula :

$\large {\boxed{m = (y_2 - y_1)/(x_2 - x_1)}}$

If point ( x₁ , y₁ ) is on the line with gradient m , the equation of the line will be :

$\large {\boxed{y - y_1 = m ( x - x_1 )}}$

Let us tackle the problem.

$\texttt{ }$

This problem is about Directly Proportional.

If (x₁ , y₁ ) and (x₂ , y₂) are on the line that represent a proportional relationship, then :

$\large {\boxed { y_1 : x_1 = y_2 : x_2 } }$

Option A

Let:

(2,4) ⇒ (x₁ , y₁)

(3,9) ⇒ (x₂ , y₂)

$4 : 2 \ne 9 : 3$

$2 : 1 \ne 3 : 1$

$2 \ne 3$ → not proportional

$\texttt{ }$

Option B

Let:

(6,8) ⇒ (x₁ , y₁)

(18,24) ⇒ (x₂ , y₂)

$8 : 6 = 24 : 18$

$4 : 3 = 4 : 3$ → proportional

$\texttt{ }$

Option C

Let:

(3,6) ⇒ (x₁ , y₁)

(9,4) ⇒ (x₂ , y₂)

$6 : 3 \ne 4 : 9$

$3 : 1 \ne 4 : 9$ → not proportional

$\texttt{ }$

Option D

Let:

(1,1) ⇒ (x₁ , y₁)

(2,1) ⇒ (x₂ , y₂)

$1 : 1 \ne 1 : 2$ → not proportional

$\texttt{ }$
