An algebra class normally has y students, but today it is just 2/3 full. Express the number of students in class today terms of

sertanlavr [38]

Answer:

2/3y

Step-by-step explanation:

If the class usually has y students and has 2/3 today, it can be represented by 2/3y.

Since multiplying a number or variable by 2/3 makes it 2/3 of the amount, 2/3y will represent the people in the class.

So, in terms of y, 2/3y represents the number of students in class today.

Find the slope of the line that passes through the points (2.1) and (-1.-1).

sp2606 [1]

Answer: The slope is $\frac{2}{3}$

Step-by-step explanation:

The slope can be calculated with the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Then, knowing that the line passes through the points (2,1) and (-1,-1), we can substitute the coordinates into the formula.

In this case:

$y_2=-1\\y_1=1\\x_2=-1\\x_1=2$

Therefore, the slope of the line that passes through the points (2,1) and (-1,-1) is:

$m=\frac{-1-1}{-1-2}\\\\m=\frac{-2}{-3}\\\\m=\frac{2}{3}$
