<u>ANSWER: </u>
The slope of the given line y - 3 = (x - 5) is 1 and (5, 3) is a point on that line.
<u>SOLUTION:
</u>
Given, line equation is y – 3 = (x – 5)
We have to find the slope of the given equation along with a point on that line.
Now, if we observe, the given equation is in point slope form 
Where, m is the slope of the line and
is a point on the line.
Now by comparison of the two equations we can conclude that,

So, the point on the given line is (5, 3).
Hence, the slope of the given line is 1 and (5, 3) is a point on that line.
To answer this item, we let x be the number of counters that Max has. By the representation, the number of counters that Jack has is 3x.
a. Ratio of counters,
3x:x
which can be simplified by dividing by x both sides of the ratio giving us the answer of,
3:1
b. Fraction of counters Max have,
fraction = x / (x + 3x) = 1/4
