Answer:
Step-by-step explanation:
The slope of the line needs to be determined first:
Now let's use that and one of the coordinates to write an equation in point-slope form:
and, simplifying,
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.
Answer:
4
Step-by-step explanation:
