Question

Which function represents Walter’s situation?

Answer 1

In a proportional relation, the intercept of the graph is the origin as given

in the graph of the question.

The function that represents Walter's situation is the option;

• y = 8·x

Reasons:

The points in the graph of the question, obtained from similar question

online are;

(1, 8), (2, 16), (3, 24)

The slope of the graph is therefore;

$\displaystyle Slope, \, m = \mathbf{\frac{24 - 8}{3 - 1}} = 8$

The equation of the graph in point and slope form is; y - 8 = 8·(x - 1)

Which gives;

y = 8·x - 8 + 8

y = 8·x

Therefore;

• The function that represent Walter's situation is; y = 8·x

The graph of Walter's situation obtained from a similar question, which shows the number of hours of sleep in relation to the number of days is attached.

The options are;

A.) y = 6·x

B.) y = 6

C.) y = 8

D.) y = 8·x
