Answer 1

Explanation:

The slope of the line needs to be determined first:

`m=(-9+-5)/(-12+-8)=(-14)/(-20)=(7)/(10)`

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

`y-5=(7)/(10)(x-8)`

and, simplifying,

`y-5=(7)/(10)x-(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.
