Question

Write an equation that gives the proportional relationship of the graph.

Answer 1

Answer:

C

Step-by-step explanation:

A proportional graph is a line. Every line has a slope. The slope is found by subtracting two points as a ratio. The line has points (0,0) and (2,6).

6-0 = 6

2 -0 = 2

The ratio is vertical over horizontal so 6/2 = 3.

The equation is y = 3x.

Answer 2

Answer:

C) $y=3x$

Step-by-step explanation:

1) Checking the coordinate points (2,6), (4,12),  (6,18), (8,24). And since the Proportionality Constant is given by

$k=\frac{y}{x}$

$k=\frac{y}{x}=\frac{6}{2}=\frac{12}{4}=\frac{18}{6}=\frac{24}{8}=3$

Then k=3

2) A Proportional Function is given by:

$y=kx$

Thus we can state that proportional function rule as:

$y=3x$
