if you put the points into the equation y2 - y1/x2 - x1 you'll end up with a zero in the denominator, which indicates a vertical slope. Basically the slope(m) is undefined
It's really easy to tell if your answer is going to be undefined if both the x values are the same (in this case they're both 9)
Answer:
About 630 seventh-grade students would like to snorkel
Step-by-step explanation:
if you do
7/9 x 90 equals 630/810 total students
<span>6/3+(-1/3)
</span><span>= 6/3-1/3
= 5/3
= 1 2/3</span>
The second choice is the answer
In grade 7, 10/18 students are members of the band.
In grade 8, 10/12 students are members of the band.
Because 10/12>10/18, the answer is B
