Answer 1

Answer:

Step-by-step explanation:

The slope of the line needs to be determined first:

$m=\frac{-9+-5}{-12+-8}=\frac{-14}{-20}=\frac{7}{10}$

Now let's use that and one of the coordinates to write an equation in point-slope form:

$y-5=\frac{7}{10}(x-8)$

and, simplifying,

$y-5=\frac{7}{10}x-\frac{56}{10}$

Now let's multiply everything by 10 to get rid of the fractions:

10y - 50 = 7x - 56

and

-7x + 10 y = -6

Apparently, they do not like to lead with negatives, which is not uncommon:

7x - 10y = 6

So his model is not correct.
