Answer:

Ok,(-5,__) means that -5 is the x intercept and the missing number is the y intercept

So, We need to substitute x with -5 in the equation to get the value of y

x-5y=-15

-5-5y=-15

-5y=-15+5

-5y=-10

-5y/-5=-10/-5

y=2

So,the missing value is 2. (-5,2)

Classrooms have a capacity of either 30 or 31 students. If 307 students are assigned to rooms that are to be filled to capacity,

There are now 7 classrooms of 31 and 3 of 30.

<h3>What is liner equation?</h3>

A linear equation in mathematics is an equation that can be written as display style a 1x 1+ldots +a nx n+b=0, where x 1, dots, x n are the variables, and display style b, a 1, ldots, a n are the coefficients, which are frequently real integers.

<h3>According to the given information:</h3>

Madison, we first have to add 30 + 31 = 61.

How many times does 61 go into 307

Five,

because 61 x 5 = 305.

This means there are 5 of each classroom.

We still have two students left over, though, so they will have to be added to two of the 30 rooms,

so there are now 7 classrooms of 31 and 3 of 30.
