ANSWER

$q = - 7p$

EXPLANATION

The constant difference of p values is

4-2=2

The constant difference of the 'q' values is

-28--14=-14

The function is of the form:

$q = m(p - p_1) + q_1$

where

$m = \frac{change \: in \:q }{change \: in \: p}$

$m = \frac{ - 14}{2} = - 7$

We plug in the values to get;

$q = - 7(p - 2) + - 14$

Expand:

$q = - 7p + 14+ - 14$

Simplify:

$q = - 7p$

Ricky can type 161 words in 7 minutes. how many can words can he type in 20 minutes.

kakasveta [241]

So 161 divide 7 equals 23 so therefor he types 23 words per minutes. 23 times 20 equals 460. I think he can type 460 words in 20 minutes.
