For the first one, it’s (1,3) - substitute the values in and you’ll get -5
For the second one, it’s (3,1)
Getting the slope of all the tables (by getting the difference between succeeding y values and x values and getting the ratio of the difference in y and difference in x), I was able to determine that the third table (31, 18) and the fifth table (12, 7) have <span>lower unit rate than the rate represented in the equation y=3/5x (which has a slope of 0.6). To prove this:
third table calculation:
m (slope) = (y2-y1)/(x2-x1) = (36-18)/(62-31) = 0.58 (less than 0.6)
fifth table calculation:
</span>m (slope) = (y2-y1)/(x2-x1) = (14-7)/(24-12) = 0.58 (less than 0.6)
They are both examples of <span>equivalent fractions. :)

The <em>correct answer</em> is:
4) 8
Explanation:
We want to find the frequency of this range. To do this, we count how many values fall between 12.0 and 13.9. There are 8 total values that do this, so the answer is 8.

Hope this helps!
