Question

Melanie uses the ordered pairs(2010,48) and (2013,59) to find her equation. Tracy defines x as the number of years since 2010 and uses the ordered pairs (0,48) and (3,59) to find her equation. How will the two girl's equations compare?

Answer 1

Answer:

The answer is "$\bold{\frac{11}{3}}$".

Step-by-step explanation:

Given value:

i) (2010,48) and (2013,59)

ii) (0,48) and (3,59)

Slope for the given point:

Formula:

$\bold{M= \frac{y_2-y_1}{x_2-x_1}}$

In point (i):

$\to M= \frac{59-48}{2013-2010}$

         $= \frac{11}{3}$

In point (ii):

$\to M= \frac{59-48}{3-0}$

         $= \frac{11}{3}$
