Answer:
at least 9 students in each cohort.
Step-by-step explanation:
Given that :
In a class, there are 25 students and each of them is either a sophomore, a freshman or a junior. We have to determine the number students in the same cohort.
Let us suppose there are equal number of students in each of the cohort.
Now let us assume that the number of the students in each cohort be 8, i.e. each as a freshman, a junior or a sophomore. Therefore, the total number in the all the cohorts will be 24 students only.
Thus, we can say that there are at least freshman, at least
sophomore or at least
junior in each of the cohort.
Answer <u>(assuming the question allows it to be written in slope-intercept form)</u>:
Step-by-step explanation:
1) First, find the slope of the equation. Use the slope formula , substitute the given points' x and y values, and simplify:
Thus, the slope is .
2) Now, use the point-slope formula and substitute real values for
,
, and
.
Since represents the slope, substitute
in its place. Since
and
represent the x and y values of a point the line crosses, use the x and y values of any one of the given points to substitute into the formula. (Either one is fine. I chose (2,-3).) Then, isolate y to put it into slope-intercept form and find the answer:
