Question

The relationship between the number of heartbeats and the time shown in the graph is proportional, determine if each ordered pair represents a point from this relationship. Select yes or no
(5,10) Yes or No

(14,7) Yes or No

(8,16) Yes or No

Answer 1

$(5, 10)$ represents a point from the given relationship.

$(14, 7)$ does not represents a point from the given relationship.

$(8, 16)$ represents a point from the given relationship.

From the graph, we can see that $(1,2)$ lies on the line, so it must satisfy its condition.

Other such points are $(2, 4), (3, 6)$.

Here we can see that the value of $y$-coordinate is always double the value of $x$-coordinate.

So, the equation can be written as $y=2x$.

For $(5,10)$

$10=2(5)$

$10=10$, which is true.

So, YES this point represents a point from the given relationship.

For $(14,7)$

$7=2(14)$

$7=28$, which is not true.

So, NO this point does not represent a point from the given relationship.

For $(8,16)$

$16=2(8)$

$16=16$, which is true.

So, YES this point represents a point from the given relationship.
