Okay to start with, since we know that a negative times a negative is a positive just ignore the negative signs, they will only make it more confusing...


3/5 • 14/9

Start by cross simplifying the 9 and 3... since they both go into 3

1/5 • 14/3 Now take

1•14 = 14.
5•3 = 15.

14/15

What is the slope that passes through the points : (-2,9) and (4,-7)
Westkost [7]

Use the slope formula below:

\large \boxed{m =  \frac{y_2 - y_1}{x_2 - x_1} }

The m-term represents the slope.

The formula is the changes of two y-points over the changes of two x-points. We are given two points. Substitute both points in the formula.

\large{m =  \frac{9 - ( - 7)}{ - 2 - 4} } \\  \large{m =  \frac{9 + 7}{ - 6}  \longrightarrow  \frac{16}{ - 6} } \\  \large{m =  \frac{8}{ -3 }  \longrightarrow  -  \frac{8}{3} }

Therefore the slope is -8/3

Answer

  • the slope is -8/3

Hope this helps! Let me know if you have any doubts.

Missing details

Which type of function model would be appropriate for this situation?

Answer:

Linear function

Step-by-step explanation:

Given

y = 0.50x +9.75

Required

The function model

A function of the form:

y = mx + b

is referred to as a linear function where

m = slope/rate

b=y\ intercept

By comparison:

m = 0.50\ b = 9.75

<em>So, it is a linear function (linear model)</em>
